An amplifier uses negative feedback to increase the input resistance and output resistance. What is the suitable feedback topology?

What would be the maximum quantum efficiency (in %) possible for a photodiode, upon which an optical pulse containing 8 x 106 photons is incident and produces 6.5 x 106 electron-hole pairs?

Tasha was given a wide range of equipment by her teacher to check the condition of a diode.

The equipment given are as follows:

i) Digital Display Meter

Which of the following equipment cannot be used to check the condition of a diode?

In a current mirror circuit, the reference current (I_o) is 5 mA, and a MOSFET (M1) connected to the reference current source has dimensions (W/L)₁ = 4. The dimensions of MOSFET (M2) to which the reference current is copied have (W/L)₂ = 8. What is the current (I_x) flowing through MOSFET M2?

Assertion (A): Two transistors, one n-p-n and the other p-n-p, are identical in all respects (doping, construction, shape, size). The n-p-n transistor will have better frequency response.

Reason (R): The electron mobility is higher than hole mobility.
