... gates of M11 and M1A. The simplest is shown in the figure on the right above. You can do better for both M1A and M3A (e.g. 4.11(b), 4.12(b), or the circuit used in class), but this is a simple place to start. The reference current source IIN can come from your bandgap circuit, but initially you can ...

P–n diode
This article provides a more detailed explanation of p–n diode behavior than that found in the articles p–n junction or diode.A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p-type semiconducting layer to an n-type semiconducting layer. Semiconductor diodes have multiple uses including rectification of alternating current to direct current, detection of radio signals, emitting light and detecting light.
