Abstract
A power supply monitor includes a droop detection circuit which receives a digital signal and converts the digital signal to an analog signal, compares the analog signal to a monitored supply voltage, and responsive to detecting a droop below a designated value relative to the analog signal, produces a droop detection signal. The droop detection circuit includes a first comparator circuit with a series of inverters including at least a first complimentary-metal-oxide-semiconductor (CMOS) inverter with an input for receiving the analog signal and a second CMOS inverter, which are both supplied with a monitored supply voltage. The inverters operate in a crowbar mode when the monitored voltage supply is near a designated level, and each include four pull-up transistors connected in two parallel legs of two transistors, and four pull-down transistors connected in two parallel legs of two transistors.
