The operational amplifier (op amp) is an important part of any analog signal chain, often working as a crucial part of the interface between sensors and our world-leading ADCs. Common analog op amp fu
This video illustrates how to use the .AC analysis to look at open loop gain and phase of operational amplifier feedback circuits in LTspice. It explains how to break the feedback loop in an op amp circuit while maintaining the correct operating point so that the plot the open loop transfe...
I happened to test TL074 in the circuit and had error. I was surprised as by specifications and being an op-amp, the output was completely unexpected. To probe further, I made the circuit schematic in LTspice, first using generic op-amp and then TL074 sub-circuit. The gener...
1 OP37 op-amp 1 OP97 ( slow settling amplifier ) 2 0.1uF Capacitors (used to de-couple the Vp and Vn power supplies) Directions: Build the test setup as shown in figure 2 below. Remember to supply power to the op amp, +5Vto pin 7 and -5V to pin 4 with 0.1uF capacitors used...

It sounds good only on low volume , I guess because the missing cap ( in LTSpice the vaweform is triangular without it ) . and R3 not directly to ground. Any recommendation for the filters Q , 4 seems to be letting to much other frequencies , so may be a Q of 10, I might need...

I use this schematic (DC voltage measured in a real circuit ) And the output voltage on the scope for Vin = 5VDC + 1Vp (1Khz) The similar things we can see on LTspice The Electrician said: However, if the + and - inputs of the rightmost opamp are reversed, the plot of Va looks...
Re: Op amp needs bias? « Reply #31 on: November 13, 2021, 01:49:48 am » I thought I'd post my latest diagram for any feedback. I managed to simulate it in LTSpice, but values may be wrong. pedal1.png (35.77 kB, 1522x768 - viewed 147 times.) Logged Zero...
This paper presents complete design guidelines for a typical fractional-order Colpitts oscillator (FOCO) with a non-ideal op-amp. These guidelines include effects of op-amp non-idealities like, open-loop dc gain, unity gain frequency and output resistance, into the design. The relation among ...
