Abstract
A circuit portion for generating an output reference voltage (V, V, V) includes a self-cascode circuit portion, a follower circuit portion, and a reference resistor (R). The self-cascode circuit portion generates a first intermediate reference voltage (V) at a first node based on an input current (I) provided thereto. The follower circuit portion mirrors the input current (I) and generates a second intermediate reference voltage (V) at a second node based on the first intermediate reference voltage (V). The reference resistor (R) is coupled to the second node. The follower circuit portion comprises includes a feedback loop that counteracts variations in the second intermediate reference voltage (V), and the circuit portion generates the output reference voltage (V, V, V) based on a current through the reference resistor (R).
