A High-Swing, High-Impedance MOS Cascode Circuit
نویسنده
چکیده
|A simple cascode circuit with the gate voltage of the cascode transistor being controlled by a feedback ampli er and thus named `regulated cascode' is presented. In comparison to the standard cascode circuit the minimum output voltage is lower by about 30 to 60% 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 ampli ers are discussed. Finally, experimental results con rming the theory are presented.
