Abstract: In an embodiment, an electronic includes a feedback-coupled circuit stage and a compensation circuit stage. The feedback-coupled stage is configured to drive a load, and the compensation stage is coupled to the feedback-coupled stage such that a combination of the compensation and feedback-coupled stages has a frequency response including a first root and an opposite second root that depend on the load. For example, an embodiment of such an electronic circuit may be a low-dropout (LDO) voltage regulator that lacks a large output capacitance for forming a dominant pole to stabilize the regulator. The regulator includes a feedback-coupled stage that generates and regulates an output voltage, and includes a compensation stage that is designed such that the frequency response of the regulator includes a zero that tracks a non-dominant output pole of the regulator so that the output pole does not adversely affect the stability of the regulator.

Abstract: A low-power wideband Power-on-Reset (PoR) and supply brown out detection circuit is proposed, wherein a technique for accurately controlling the PoR trip points and hysteresis voltage is presented. The PoR circuit includes a CMOS circuit with asymmetric rise and fall delays for monitoring wideband supply voltage transients including supply brown out. Being a non-bandgap and non-comparator based circuit, it consumes a very small power and Si area.
