About this document
Constant-gm Circuit in Reference Design by Aram Shishmanyan is a document available to read on EtoBox.
The bandgap reference circuit generates a temperature independent reference voltage (VREF) by combining positive and negative temperature coefficient components. The positive temperature coefficient (PTAT) component comes from the base-emitter voltage difference (ΔVBE) between two bipolar transistors, which increases linearly with temperature. This PTAT component is combined with a negative temperature coefficient (CTAT) component, typically the base-emitter voltage of a single transistor, to generate a zer
