Consider the oscillator circuit shown below. The op amp i s ideal Rb Vo R2 = 10 kΩ L2 100 mH R1 1 k2 L1 = 10 mH a. What is the frequency of oscillation in Hz? b. Specify the required value of Rb sustain oscillations. c. A limiter circuit is added to oscillator by separating Rb into two series resistors Rb1 and Rb2 as shown in the next page along with two anti-parallel diodes in shunt with Rb2. determine...
Problem 2: In the circuit shown assume the Op-Amp is ideal. A) Find vo as a function of vi and vs. B) Next assume the Op-Amp is ideal, except its low frequency gain is Ao= 100 V/V. Now find vo as a function of vi and v2. C) The Op-Amp has a terminal frequency of fi 10° Hz, find the -3 dB (corner) frequency of the output signal w2 10K
2. For the circuit below, the n-channel enhancement MOSFET is biased to have gm-4 mA/V Find the mid-band voltage gain AM Design the bypass and coupling capacitors to have the three low frequency poles at 50 Hz, 10 Hz and 3 Hz, respectively. It is the rule of thumb to have a minimum total capacitance. What is the fi? If a Rs-500 Ω is inserted between the source and Cs. What the Cs should be for a same pole frequency...
