Abstract: A circuit includes a first transconductance stage having an output. The circuit further includes an output transconductance stage, and a first source-degenerated transistor having a first control input and first and second current terminals. The first control input is coupled to the output of the first transconductance stage. The circuit also includes a second transistor having a second control input and third and fourth current terminals. The third current terminal is coupled to the second current terminal and to the output transconductance stage.

Abstract: An automatic charge/discharge circuit is presented that allows a current mirror circuit with a high capacitance to quickly and automatically charge or discharge the capacitance in order to allow for a fast start-up power supply. The charge/discharge circuit automatically stops charging or discharging as the voltage on the capacitance approached a desired steady state.
