Perform a simple initial design of an ac coupled common-emitter amplifier with four resistor biasing and emitter by-pass capacitor, to have a voltage gain of about 100, for the following conditions. Justify any approximations used. (Assume Ic=1/300 A) i)Transistor ac common-emitter gain, B, 100 ii) Supply voltage ofV0c-20V iii) Allow 10% Vcc across RE DC collector voltage of 10 V iv) v) DC current in the base bias resistors should be ten times greater than the DC base current. Assume...
(a) Design an inverting amplifier by choosing suitable resistor values for R1 and R2 to produce a gain of 5 when both switches Sw1 and Sw2 are open. (b) Design the bias input circuit by choosing suitable resistors R3 and R4 such that the voltage vb will be 0.5V if the positive power supply of the op-amp is connected to a 5V battery. Again both switches are open. (c) Given Sw1 is open, the amplifier is turned on for enough...

Problem 3: Design Problem On Figure P3a, you have a Common Source (CS) n-channel MOSFET amplifier. Notice the absence of a source resistor Rsig and load resistor R. If we know how the present amplifier (the one on Figure P3a) behaves without Rsig and RL, we can infer its behaviors if Rsig and R were to be added. design the amplifier circuit on Figure P3a, i.e., you have to find appropriate values for RGj You are to RG,, RD, and...
