Equivalence in circuits
I'm studying circuit theory, with only linear elements and no capacitors or inductors or mutual inductances, so no differential equations. All the sources (current and voltages) are constant.
To be ...

Overshoot Before Transition
First of all, a little bit of context: I'm designing a single-supply Howland current source using the OPA357 (rail-to-rail 200MHz OPAMP) to delivery 100uA of AC current up to 1MHz. In one of my ...

Cheap, low-quality constant-current sink over wide voltage range
I'm looking for a cheap (as in: low component count, low PCB area, low component cost) way to put >= 1mA of load on a voltage that may be anything from 1.2 to 17 volts (minimum required load on a LDO ...

Current Source Transformation
So my question is: Can I transform the current source I1 with R5 into a voltage source? I know for sure that if R3 was not in between them I could, but does it make a difference? I am not sure.

Trying to make a current source with an XRP29302 (linear regulator)
I'm familiar with the configuration to make an LM317 (voltage regulator) into a current source. You connect a resistor between the Vout and Adj pins (Say 1.24 ohms) and draw the output directly from ...

0-5V Voltage controlled Constant Current Source with High & Low current Offset
I am trying to design a MOSFET constant current generator controlled by a 0 - 5VDC signal (non pwm). I have had no problems getting a nice resistor divider and an op amp to control the circuit. I am ...
