Abstract
A supply-independent biasing circuit applied to a bandgap reference circuit or a proportional to absolute temperature (PTAT) current generating circuit. The bandgap reference circuit or the PTAT current generating circuit includes a mirroring circuit, an operation amplifier, and an input circuit. The mirroring circuit including a plurality of first type FETs. The operation amplifier includes a first type FET connecting to a current input terminal of the operation amplifier. And, the supply-independent biasing circuit includes a first type FET having a gate connected to gates of the first type FETs in the mirroring circuit and having a drain acted as an output current path; and, a current mirror including a plurality of second type FETs and having a current receiving terminal connected to the output current path and having a current outputting terminal connected to the current input terminal of the operation amplifier.
