An amplifier is characterised by a 3 pole transfer function of the form where Ao - 100,000, f1( 1/2) 1e4 Hz, f2 1e6 Hz, f3 -100e6 Hz By drawing a Bode plot for the amplifier loop gain (or otherwise), determine the phase margin for the amplifier when used with a feedback factor, B-0.5 An amplifier is characterised by a 3 pole transfer function of the form where Ao - 100,000, f1( 1/2) 1e4 Hz, f2 1e6 Hz, f3 -100e6 Hz...
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...
A common source amplifier circuit based on a single n-channel MOSFET is shown in Figure 4b. Assume that the transconductance gm-60 mS (equivalent to mA/ V) and drain source resistance, os, is so large it may be neglected. 0) Calculate the open circuit voltage gain Av Yout/ Vis. i) The amplifier has a load of 10 k2. Determine the current gain Va. = 12 V 150k 4k3 Vout Vin 200k GND = 0 V Figure 4b a) State the name...
