ii. The slew rate of an op-amp is defined as the:  (i) Maximum rate of change of output voltage with time (ii) Minimum rate of change of output voltage with time (iii) Moderate rate of change of output voltage with time (iv) None of the above

3. In an ideal op-amp, which is not true? a) Open loop voltage gain is infinite b) Input resistance is infinite c) Slew rate is infinite d) CMRR is zero

For the summing Op-Amp, find the output voltage Vout?

has been determined that a certain op-amp has three internal critical frequencies, as follow 1.2 kHz, 50 kHz, and 250 kHz. If the midrange open-loop gain is 100 dB, is the amplifier configuration stable, marginally stable, or unstable?

Operational Amplifier (Op-Amp) is a solid-state device with voltage amplification capabilities as shown in Figure Q1. (a) Name the function of Op-Amp U1, U2 and U3 in Figure Q1. (b) Derive the output voltage (Vol, Voz and Vo3) of each Op-Amp in Figure Q1. Based on derivation in Q1(b), calculate the output voltages (Vol, Vo2 and Vo3) of the circuit. All the Op-Amps are powered with + 12V voltage supplies. Given: Ra = Rb = 1 kN, Ry = Rx = 10 kN, Ra = 3.6 kN, Rr = 3 k2. The input voltages: V,= V = 5 V. (c) (d) Draw and label clearly the sinusoidal output of Vo1, Vo2 and Vo3.
