Simple and hold circuit using op amp Circuits Wiring diagram

As the name indicates , a sample and hold schema is a schema which samples an input signal and holds onto its last sampled value until the input is sampled again. Sample and hold diagram are commonly used in analogue to digital converts, communication diagram, PWM diagram etc. The schema shown below is of a sample and hold schema based on uA 741 opamp , n-channel E MOSFET BS170 and few passive components.

Description

As the name indicates , a sample and hold schema is a schema which samples an input signal and holds onto its last sampled value until the input is sampled again. Sample and hold diagram are commonly used in analogue to digital converts, communication diagram, PWM diagram etc. The schema shown below is of a sample and hold schema based on uA 741 opamp , n-channel E MOSFET BS170 and few passive components.

In the schema MOSFET BS170 (Q1) works as a switch while opamp uA741 is wired as a voltage follower. The signal to be sampled (Vin) is applied to the drain of MOSFET while the sample and hold control voltage (Vs) is applied to the source of the MOSFET. The source pin of the MOSFET is connected to the non inverting input of the opamp through the resistor R3. C1 which is a polyester capacitor serves as the charge storing device. Resistor R2 serves as the load resistor while preset R1 is used for adjusting the offset voltage.

During the positive half cycle of the Vs, the MOSFET is ON which acts like a closed switch and the capacitor C1 is charged by the Vin and the same voltage (Vin) appears at the output of the opamp. When Vs is zero MOSFET is switched off and the only discharge path for C1 is through the inverting input of the opamp. Since the input impedance of the opamp is too high the voltage Vin is retained and it appears at the output of the opamp.

The time periods of the Vs during which the voltage across the capacitor (Vc) is equal to Vin are called sample periods (Ts) and the time periods of Vs during which the voltage across the capacitor C1 (Vc) is held constant are called hold periods (Th). Taking a close look at the input and output wave forms of the schema will make it easier to understand the working of the schema.

Input and output waveforms - Sample and hold schema

Notes

The schema can be assembled on a vero board.
Use +15V/-15V DC dual supply for powering the opamp.
Capacitor C1 must have minimum leakage current possible and thats why a polyester capacitor is used here.
Mount the IC uA741 on a holder.
The type number of the MOSFET Q1 is not very significant here and so substitution is possible if BS170 is not available.
BS170 is a 60V, 500mA n-channel enhancement mode MOSFET available in TO-92 package.
Preset resistor R1 can be used for offset adjustments.

Batteries Charger PSU Ideal for Digital Cameras

This circuit was created for digital cameras. Its known the digital cameras have considerable power consumption. For example my camera Minolta E223 requires approximately 800 mA. In practice a mains power supply or high capacity NiMH accumulators (batteries) can satisfy this demand. Batteries Charger & PSU Circuit diagram: This circuit consists of two parts, charger and adapter. The transformer, rectifier bridge and buffer condensator are common. Adapter is quite simply its main part is an adjustable voltage regulator LM 317 according to usual setting. Output is a suitable for camera jack plug. Voltage can be adjusted in range 2-9 V. In the charger circuit a 7805 fixed voltage regulator works as current generator assured constant current during charging. This charging current can be adjusted with the 100 /1W potentiometer in range about 50-300 mA indicated by a small current measuring instrument. From one to four batteries can be charged simultaneously. The switch must be set according to number of batteries, and charging current of batteries given by manufacturer must be adjusted. This circuit doesnt measure charging time and charging condition of batteries. Manufacturers give charging time, usually 14-16 h. I solved this problem with a simply, cheap mechanical mains timer. I think its accuracy is sufficient.

Ultrasonic Wave Receiver Circuit

Ultrasonic Wave Receiver

Ultrasonic recipients will receive an ultrasonic signal emitted by an ultrasonic transmitter in accordance with the characteristic frequency. Received signal is going through the process of filtering using the frequency band pass filter circuit, with a frequency value that is passed has been determined.

Proteus VSM Software

The most powerful CAD system, allowing virtually simulate work a huge amount of analog and digital devices.

Proteus VSM software package allows you to build a scheme of any electronic device and simulate its performance, identifying mistakes made at the design stage and tracing. The program consists of two modules. ISIS - Editor of electronic circuits, followed by imitation of their work. ARES - editor PCB autorouter equipped Electra, built-in editor libraries and automatic placement of components on the board. Besides ARES can create a three-dimensional model of the PCB.

Proteus VSM includes more than 6,000 electronic components with all reference data, as well as demonstration projects study.The program has the tools and USBCONN COMPIM, which allow you to connect virtual device to the USB port and the computer COM.When connecting to these ports any external device virtual circuit will work with it as if it existed in reality.Proteus VSM supports the following compilers: CodeVisionAVR and WinAVR (AVR), ICC (AVR, ARM7, Motorola), HiTECH (8051, PIC Microchip) and Keil (8051, ARM).You can export models of electronic components from the program PSpice.

Despite the fact that the program works with devices consisting of several microcontrollers and even with chips from different manufacturers in a single device, you must clearly understand that the simulation replicates the real work schemes are not exactly!To avoid errors, you need a clear idea of the final result.

Proteus VSM is a commercial product. There is a free demo version. It has all the features and capabilities of pay package, but you can not save or print the result of the work to create your own microcontroller.

English-language program menu. Complete localization system for Proteus VSM not. You must install the program in a folder without Cyrillic characters in the title.

Operating systems, which employ this CAD - is Windows 2000 / XP / Vista / 7. Note that Proteus VSM functional in Windows 7, but starting with version 7.8.

Distribution of the program: Shareware (fee required), the price - from £ 99
