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