Abstract:
A two-quadrant regulator providing a stable output Vo, comprising:an output current source circuit; an output current sink circuit; a source of reference voltage Vref; a source of bias voltage Vbias; a stabilizing circuit coupled to said output current source circuit, to said output current sink circuit, to a fraction k (0said stabilizing circuit configured to couple a signal proportional to (kÂ·Voâˆ’Vref) to an input node of said output current sink circuit, and to couple a signal proportional to (Vbiasâˆ’kÂ·Vo+Vref) to an input node of said output current source circuit; wherein said stabilizing circuit transitions said output current source circuit and said output current sink circuit between conductive and non-conductive states to stabilize magnitude of said Vo as a function of relative magnitudes of kÂ·Vo and Vref and Vbias.
