Abstract
A circuit includes a divider circuit block configured to generate a trim term signal (VBG_TRIM) that is temperature and process independent. The circuit further includes a processing circuit block configured to multiply a temperature dependent reference voltage signal (TAP_GG) by a factor, and to sum the trim term signal with a result of the multiplication to generate an output reference voltage (VGG).
