Abstract
This disclosure relates to a power supply detection circuit, including: a first input stage field effect transistor; an inverter stage; and a feedback stage field effect transistor. The inverter stage includes a complimentary pair of transistors that includes an NMOS transistor and a PMOS transistor configured and arranged such that gate lengths of the PMOS and NMOS transistors are different. The disclosure also relates to an integrated circuit including a power supply detection circuit.
