Best place to add DC biasing
I'm working on a circuit where I have a CS4344 audio DAC feeding into a LM324 inverting amplifier that uses 1.2v as a reference voltage.
I'm staring with the example circuit shown in the CS4344 ...

Please provide your comments on this circuit idea of mine for bias generation?
There is a requirement for a P-side current generation. Currently we have P-side Vt/R solution which is the left branch in the figure, except it is diode connected. When the PMOS is diode connected, ...

Do FETs need to be biased?
From my knowledge, BJTs need to be biased to control its linearity and gain, usually with resistors on the base and collector.
Suppose I want a FET in saturation acting as a high-side switch.
Do FETs ...

AC analysis of a Bias Tee
I am designing a bias tee here and wondered whether it actually works or not? Hence I conducted an AC analysis instead of S-parameters (after verifying that s parameters are okay). The bias tee has ...

Non inverting opamp with bias DC
I'm doing a lab work on a circuit that takes a square signal in the input and first amplify it, then shape it and the amplify it again. So the circuit is actually composed by: an amplifier (inverting),...

Can a capacitor be used for biasing?
I have a load switch IC SiP32431DN which internally has a comparator at its input stage (connected to its on/off pin). If I connected a, let's say, 100nF capacitor to this on/off pin, would that be ...

Instructables DIY current limiter circuit [duplicate]
I found this inline and was hoping if that circuit is okay. Instead of a battery though, I want to use a dynamo (plenty of juice-wise).
Output of dynamo is 18 V 200 mA. I wish I could adjust the ...
