Title:
ADAPTIVE BIAS CONTROL FOR A VOLTAGE REGULATOR
Document Type and Number:
WIPO Patent Application WO/2021/127614
Kind Code:
A8
Abstract:
A circuit (310) includes first and second transistors (M11 and M12), an adaptive bias current source circuit (125), and an adaptive resistance circuit (320). The first transistor (M11) has a control terminal and first and second current terminals. The control terminal of the first transistor (M11) being a first input to the circuit (310). The second transistor (M12) has a control terminal and first and second current terminals, and the control terminal of the second transistor (M12) is a second input to the circuit (310). The first and second inputs are differential inputs to the circuit (310). The adaptive bias current source circuit (125) is coupled to the second current terminal of the first transistor. The adaptive resistance circuit (320) is coupled between the second current terminal of the second transistor (M12) and the adaptive bias current source circuit (125).
