This is regarding the biasing of a second order Sallen-Key low pass filter. The filter seems to work fine when I use a sinusoidal input in LTSpice and produces an output centered around 1.65 V. ...

I'm studying old equipment BJT amplification, and I often see this kind of biasing design I reproduced in circuitJS (and seems to work very well): The AC generator on the left is a tape recorder play ...

I'm trying to make an amplifier with a common base input followed by an emitter follower, and I'm getting outrageous distortion figures when I simulate it in Multisim. For example, for a 5 mV (10 mV p-...

So here how I get it, it is the drains of pMOS and nMOS are shorted, which implies it is like two current sources joined and both have same direction. For (a), to ensure that both the saturation ...

I have a non-contact current sensor with a ±2 V output (10–15 Ω source impedance). I need to shift it by +2 V to get 0–4 V (and then I will scale it to 0-3.3V) for my ADC. I have looked at three ...
