Positive Pulse Pulse Stretcher
A simple pulse stretcher built with two sections of an operational amplifier uses a voltage follower U1A to drive D1 and C2. C2 charges to the peak value of the pulse voltage. Resistors R3 and R4 determine the discharge time...
741 Astable Timer
In this circuit, a standard operational amplifier (op-amp) is configured as an astable multivibrator. The output is non-symmetrical, but it has the advantage of being controlled by only one resistor and one capacitor: a 100k variable resistor (U2) and a...
Capacitor internal resistor meter
The design presented here works by applying a 50kHz, 200mV square wave to the capacitor under test, in series with a 10 Ohm resistor. The AC voltage appearing across that resistor is measured and displayed on a meter. So the...
Basic-track-and-hold-sample-and-hold
Feedback operates similarly to a conventional operational amplifier (op-amp) voltage follower, providing 11 unity-gain, non-inverting outputs. This configuration also features a very high input impedance. The primary distinction between a track-and-hold and a sample-and-hold lies in the duration for which...
Guitar Control
The IC1A operational amplifier is configured as an inverting amplifier, with its gain determined by a three-way switch that connects different resistor values in parallel to R4. Following this input stage is an active three-band tone control circuit, designed to...
Precision-full-wave-rectifier
This circuit provides accurate full-wave rectification. The output impedance is low for both input polarities, and the errors are small at all signal levels. It is important to note that the output will not sink heavy currents, except for a...
adj pwr
The design incorporates a universal capacitor mounting and spacing feature, enabling compatibility with various capacitor types. It includes a mounting pattern suitable for TO-200 or TO-218/247 packages, specifically for the pass transistor and the transistor utilized in the current limit...
op amp Amplifying signal from CO2 Sensor
Amplify a MG811 CO2 sensor to a range readable by an ATMEGA2560 (0-5V). Other analog sensors are in use, so it is preferred not to change the reference voltage on the ATmega. A module that scales the signal has been...
op amp How does this OP-AMP offset voltage measuring circuit work
This circuit is constructed using two LT1001 operational amplifiers (OP-AMPs), with the output of the OP-AMP saturating at +5V. The power supplies used are +5V and ground. According to the documentation, applying +1V to the "Servo Input" results in an...
