The input capacitance to an STM amplifier is 2pF. The desired frequency response is 5kHz (i.e., 0.0002 s time constant). Choose the largest current to voltage conversion resistor this constraint allows, and then calculate the smallest measureable current (i.e. just equal to the Johnson noise) at the target bandwidth. The angular'frequency, ω, at which the response of an RC integrator falls by 3dB is given by ωRC=1. I need step by step equation with explanation please. Thank you
