Unformatted text preview: Current mirror: The circuit (including which transistor should be diode connected, pull-up PMOS mirrors and pull-down NMOS mirrors), how V GS and (W/L) for the bias transistor (the one in series with I REF ) will be determined (notice V GS is then the same for all other transistors), and the v OUTi range to keep every transistor in saturation. Finally, current steering circuits to transfer between pull-up PMOS mirrors to pull-down NMOS mirrors. Use Questions 11 and 12 of the prelim exam last year (the entire exam will be posted) for practical calculation if there is sufficient time....
