This is a summing amplifier circuit. This is an inverting circuit that provides an inverted output equal to the sum of all three input. This circuit has some advantages such as there is no interaction between the operation and inputs, and also it is very easily to implement the weighted averaging and summing on this circuit. Here is the circuit: […]

Not only a summing circuits, but there are also subtracting circuits. Here’s the circuit diagram: Subtracting circuit is a common application which is used to eliminate the vocal track (recorded at equal levels in both channels) from stereo recordings. R1 = R3 and R2 = R4, Vout = (R2/R1)(Vin2 – Vin1) R1||R2 = R3||R4 for minimum error due to input […]

This is a 1st order ALL pass filter circuit. All frequencies are allowed at the same gain by this circuit. Here is the schematic diagram of the circuit: We can change the signal’s phase using this circuit. This circuit can be used to correct the phase of the signal as well. At F(90) this circuit has a 90° phase shift. […]

Two reasons why LM101 is well suited to comparator applications are it has a large differential input voltage range and the output is easily clamped to make it compatible with various driver and logic circuits. LM101 doesn’t have the speed of the LM7104 (10us versus 40 ns, under equivalent conditions) but spees is not a problem in many linear applications […]
