1-kΩ load. Associated with each stage is a parasitic input
capacitance (to ground) of 10 pF and a parasitic output capacitance
(to ground) of 2 pF. Parasitic capacitances of 5 pF and 7
pF also are associated with the signal-source and load connections,
respectively. For this arrangement, find the three poles
and estimate the 3-dB frequency fH.
