WebMay 31, 2024 · In addition, bandgap circuits. based on conventional PTAT sources are designed as a reference. The circuits have been implemented in a I-pm BiCMOS process. What does PTAT stand for? Acronym. Definition. ... In this way, by means of a current mirror and a current-to-voltage converter we apply again a current-keeping negative feedback. WebAs the current of the current source subcirc at the level of uit is nanoampere, due to the effect of current mirror, the whole MOSFETs of the reference voltage generator operates in subthreshold region. From (5),the difference of the gate-source voltage ∆. V. GS. of two subthreshold MOSFETs can be expressed as . 2 12 1. GS GS GS T. ln . K VV ...
