WebDec 6, 2010 · The op-amp in the circuit shown is ideal (please see attachment). The adjustable resistor RΔ has a maximum value of 160 kΩ and α is restricted to the range of 0.22 ≤ α ≤ 0.7. (a) Calculate the range of v o if v g = 40 mV (b) If α is not restricted, at what value of α will the op amp saturate? Homework Equations WebJul 5, 2024 · As you can see the circuit is pretty simple, it consists of a op-amp which drives a transistor. The output current from the transistor is fed to a LED, this output current can be varied from 0mA to 20mA by varying the potentiometer and can be measured by a Ammeter connected as shown above.

WebThe output stage of a CMOS op amp consists of common source PMOS and NMOS transistors, and gain is taken in the output stage. The gain is gm × R L, and to get a reasonable value of transconductance, the drive circuit is designed to set the quiescent current to a certain value. WebQuestion: If the opamp is ideal, can you show that the input current is equal to the output current? Show transcribed image text. Expert Answer. Who are the experts?
