GATE EC 2016 Question Paper (30-Jan-2016) (Shift 1)

A p-i-n photodiode of responsivity 0.8A/W is connected to the inverting input of an ideal opamp as shown in the figure, +V${}_{cc}$ = 15 V, −V${}_{cc}$ = −15V, Load resistor R${}_L$ = 10 kΩ. If 10 μW of power is incident on the photodiode, then the value of the photocurrent (in μA) through the load is ________

Identify the circuit below.



Note: Change in the above connection
OP4 is connected to IP7
OP5 is connected to IP6
Rest connections are same

The functionality implemented by the circuit below is

In an 8085 system, a PUSH operation requires more clock cycles than a POP operation. Which one of the following options is the correct reason for this?

The open-loop transfer function of a unity-feedback control system is

$\mathrm{G}\left(\mathrm{S}\right)=\frac{\mathrm{K}}{{\mathrm{s}}^2+5\mathrm{s}+5}$

The value of K at the breakaway point of the feedback control system’s root-locus plot is _______.
