The operational amplifier below has a specified input-bias current IIBup to 250nA and a maximal input-offset voltage VOS of ±3mV. It has a unity-gain frequency (gain-bandwidth product) of 1MHz.
a) Determine the bandwidth of the closed-loop voltage gain Vo / Vin.
b) Determine the range of dc output voltages due to the input-offset voltage VOS. (Note that Vin is an ac voltage source; it is considered to be a short-circuit in dc analyses).
c) What is the dc output voltage due to the input-bias currents IIB?
