Abstract:
A voltage level shifting circuit may include a differential first-stage level shifter that receives a binary input signal and generates a non-inverted first-stage shifted output signal and an inverted first-stage shifted output signal, a second-stage level shifter that receives the first-stage shifted output signals and generates a non-inverted second-stage shifted output signal and an inverted second-stage shifted output signal, and a signal generator that generates a level shifted final output signal corresponding to the binary input signal that is based on the non-inverted second-stage shifted output signal and the inverted second-stage shifted output signal. The voltage swing of the first stage output signals may be limited to swing between a non-zero lower value and an upper value that is less than or equal to a source-to-drain voltage rating of transistors in the differential first-stage level shifter.
