Title:
CIRCUIT FOR CANCELING THERMAL HYSTERESIS IN A CURRENT SWITCH
Document Type and Number:
WIPO Patent Application WO2003065395
Kind Code:
A3
Abstract:
A current switch including a first transistor (Q9) and a second transistor (Q10) connected as a differential transistor pair and receiving a differential logic signal (OUTX, OUT) at their bases, and logic signal controlling circuitry (Q11, Q12, R1, R2) coupled to the first and second transistors for offsetting a transition starting point of the differential logic signal to offset a self-heating induced shift in a switching threshold of the current switch.
