Abstract
Aspects of the present disclosure include a scalable proportional to absolute temperature (PTAT) hybrid circuit, comprising a bias mirror circuit configured to provide a zero temperature coefficient (ZTC) current, a PTAT control circuit configured to generate, based on the ZTC current, a PTAT current with a slope having a non-zero value, alter the PTAT current by at least scaling the PTAT current or changing the slope of the PTAT current to generate an altered PTAT current, and provide the altered PTAT current, a hybrid circuit configured to receive the ZTC current and the altered PTAT current, and output a larger current of the ZTC current and the altered PTAT current as a hybrid current.
