Abstract
An example photodiode emulator circuit includes: a first current source circuit; first and second transistors having sources coupled together and coupled to an output of the first current source circuit, a drain of the second transistor coupled to a first node; a third transistor coupled between a drain of the first transistor and a replica load circuit; a second current source circuit coupled to the first node; a capacitor coupled between the first node and electrical ground; and a fourth transistor having a source coupled to the first node and a drain that supplies an output current.
