List of top Analog Electronics Questions on Characteristics of ideal and practical operational amplifiers asked in GATE IN

A 1 kHz sine-wave generator having an internal resistance of 50Ω generates an open-circuit voltage of 10 Vp-p. When a capacitor is connected across the output terminals, the voltage drops to 8 Vp-p. The capacitance of the capacitor (in microfarads) is _________.
A resistor ladder digital-to-analog converter (DAC) receives a digital input that results in the circuit having the state as shown in the figure. For this digital input, the Thevenin voltage, \( V_{th} \), and Thevenin resistance, \( R_{th} \), as seen at the output node are _________
In the bandpass filter circuit shown, \( R_0 = 50 \, \Omega \), \( L_0 = 1 \, \text{mH} \), \( C_0 = 10 \, \text{nF} \). The Q factor of the filter is _________ (round off to two decimal places).

The output \( V_o \) of the ideal OpAmp used in the circuit shown below is 5 V. Then the value of resistor \( R_L \)in kilo ohm (kΩ) is:

The circuit shown below uses an ideal OpAmp. Output \( V_o \) in volt is \(\underline{\hspace{2cm}}\) (rounded off to one decimal place).
