| Jul 24, 2017 at 17:50 | comment | added | Andy aka | I don't like your explanation but I like mine.... M1 is a source follower so it sets a near constant voltage on M2 drain. This means M2 doesn't suffer from miller capacitance effects. Current through M2 drain is transferred to a voltage at M1 drain because of the high compliance of the current source (normally a resistor). | |
| Jul 24, 2017 at 17:38 | comment | added | Jo123 | Yes, the output impedance of a common source amplifier is high because the MOSFET ID-VDS characteristics show in saturation nearly a horizontal line. Right? So if the upper explanation is not accurate, is it possible at all to explain it in a descriptive way, let's say based on the MOSFET characteristics? | |
| Jul 24, 2017 at 16:27 | comment | added | Andy aka | If you are asking questions about the output impedance being high then you are not beginning at the right point. Do you understand why the output impedance of a common emitter (or common source) amplifier is high? | |
