1. A sinusoidal oscillator circuit is shown below. The op amp is ideal.
a. The oscillation frequency is to be 50 kHz. What is the required value of the inductance
b. What is the
Discussion Problem #11
The circuit shown below produces either square waves or triangle waves, depending on which
output, Vo1 or Vo2 is selected. The frequency can be varied over a considerable range by the
setting of the potentiometer sh
Discussion Problem #8
Two identical amplifiers (A1 = A2) are cascaded together and negative feedback is
implemented around the combination as shown below.
Discussion Problem #2
Consider the MOSFET-Based differential amplifier shown below.
KP = pCox = 5x10-5A/V2
Vt = 1 V
VA = 50 V
1. The dc power drawn from the bias supp
Discussion Problem #1
Consider the shown below composed of a Wheatstone bridge driving a difference amplifier.
The op amp is ideal. Assume that the difference amplifier does not load the Wheatstone
Discussion Problem #12
The circuit shown below is a monostable multivibrator. The op amp is ideal except that its
output limits at plus and minus 10 V.
1. What is the stable state of the circuit (v
