摘要：

— A simple cascode circuit with the gate voltage of the cascode transistor being controlled by a feedback amplifier, and thus named a “regulated cascode,” is presented. In comparison to the standard cascode circuit, the minimum output voltage is lower by about 30 to 60 percent while the output conductance and the feedback capacitance are lower by about 100 times. An analytical large-signal, small-signal, and noise analysis is carried out. Some applications like current mirrors and voltage amplifiers are discussed. Finally, experimental results confirming the theory are presented. © 1990 IEEE
