Abstract
The present disclosure provides a reference one time programmable (OTP) cell, wherein the reference OTP cell can generate a reference bias current in at least a programmed-on configuration; a current mirror coupled to an output of the OTP cell, wherein the current mirror includes at least two gate-coupled field effect transistors (FETs); wherein a current gain of a second of the two FETS is a fraction less than one of a first of the at least two gate-coupled FETs; a programmable OTP memory bit element (OTPMBE) coupled to an input of the current mirror; and a comparator having an input coupled to a node between the OTPMBE and the current mirror.
