Abstract:
1. An apparatus including an integrated circuit (IC) with metal oxide semiconductor field effect transistor (MOSFET) circuitry for generating a reference signal having a value which remains substantially constant over variations in one or more of the processing (P) of, power supply voltage (V) for and operating temperature (T) of said IC, comprising: current source circuitry to provide at least one reference current having a current value I; first reference resistance circuitry having a first resistance value R a first reference MOSFET having a channel width dimension, coupled to said first reference resistance circuitry terminal and responsive to reception of said first reference voltage by conducting a first mirrored current and providing a first bias voltage; current mirror circuitry coupled to said first reference MOSFET and responsive to reception of said first bias voltage by providing said first mirrored current and a second mirrored current; and a second reference MOSFET having a channel width dimension approximately equal to 1/N
