Shoubao Yan,Gerald W. Steele,David R. Baum +2 more
- 14 Oct 2008
TL;DR: In this paper, a differential amplifier (1D) is defined, which includes circuitry (5,R1,R2,52) coupling a common mode component of an input voltage (Vin+−Vin−) to a maximum voltage selector circuit (53) that produces an internal voltage equal to the larger of a first supply voltage.

Over-current protection circuit and method
Vadim V. Ivanov,David R. Baum +1 more
- 19 Apr 2001
TL;DR: In this paper, overcurrent protection is accomplished in an output transistor (MP) of an electronic circuit wherein an input signal (Vgatedrive) is Applying to a first conductor coupled to a gate of the output transistor to cause an output current (Iout) to flow through the output transistors and an output terminal of the electronic circuit.
