Methods and apparatuses for a CMOS-based process insensitive current reference circuit: United States Patent 9977454

By: Krishnamoorthy, Hareesh Pathamadai

Disclosed are apparatuses and methods for implementing CMOS-based, process insensitive current reference circuit(s). An apparatus includes a constant transconductance circuitry including a first and second current mirrors and respectively generating constant currents across one or more process corners, a resistive transistor in the constant transconductance circuitry having a resistance, and a feedback circuitry coupled with the resistive transistor and the constant transconductance circuitry to form a constant current source. The apparatus may optionally include a data processing module as well as another constant transconductance circuitry, another resistive transistor, and another feedback circuitry that form another constant current source. A method for implementing a system on chip may identify first and second currents generated by process insensitive current circuits, determine first and second temperature dependent voltages, and generate a digital output by transforming the first and second temperature dependent voltages.
