The circuit shown in Fig. 4 provides transfer characteristics with 7.5 V levels at the output vo. When v 0 V, a current of 0.5 mA flows in the feedback resistor (R2) and a current of 1.0 mA flows through the zener-diodes. Assume that the output saturation levels of the op-amp are +12.0 V, the forward-drop voltage of the zener-diode is 0.7 V, and the value of R, is equal to R2. a) Specify the zener-voltages of the zener diodes. b) Find the values of all resistors.

TRUE OR FALSE1. Due to the infinite open-loop volatge gain of an ideal op-amp, its diferrential input voltage should approach zero for the output voltage to be finite.2. An op-amp is a voltage amplifier circuit with very high gain, very high input resistance, and a very high output resistance.3. The input resistance of an ideal op-amp is infinite resulting to the simplifying condition that the voltage at the non-inverting input is essentially equal to the voltage at the inverting input.4. For an op-amp differentiator circuit, if the input voltage is a sine wave then the output is also a sine wave that is in-phase with the input.5. The gain of a non-inverting amplifier can be adjusted to values less than 1 or greater than 1 by using appropriate values of the external resistors.
