Power switch implementation for low voltage digital circuits

This letter presents a novel power switch structure using only low threshold voltage MOSFETs to extend the power switch to ultra-low voltage region. The proposed structure deploys seriesconnected low-Vth footers with two virtual ground ports and selectively chooses the logic cells for connecting to each virtual ground port according to the delay criticality. Moreover, additional circuitries are...

Low-power LVDS for digital readout circuits

This paper presents a mixed-signal LVDS driver in 90 nm CMOS technology. The designed LVDS core is to be used as a data link between Infrared Focal Plane Array (IRFPA) detector end and microprocessor input. Parallel data from 220 pixels of IRFPA is serialized by LVDS driver and read out to microprocessor. It also offers a reduced power consumption rate, high data transmission speed and utilizes...

Circuits for Low Power Digital Signal Processing

It is predicted that at the 90nm technolony node, leakage power will surpass dynamic power. This poses several challenges to high-speed circuit designers. By the same token, the complexity of low power, low operating frequency designs is threatened more and more by static power dissipation concerns. It has been recently shown that if energy per operation (EOP) is used as an optimization metric,...
