This paper presents a new approach using simultaneous voltage-scaling and gate-sizing for low power without violating the timing constraints. We provide the problem formulation in this application, and propose algorithms for single voltagescaling, single gate-sizing, and their simultaneous manipulation. We target a globally optimal solution by showing how the power optimization is related to th...

Analog switches, which are known to be the bottle-neck for reducing the supply voltage, are analyzed. MOSFET transistors with channel lengths shorter than the minimum feature size (L 0 ) in a given technology are proposed for use as switches operated at a low supply voltage. These MOSFETs have lower threshold voltage and higher punchthrough currents compared to a transistor of L 0 length (due t...

A Level shifter used in multiple voltage digital circuits is presented. Level shifter allow for effective interfacing between voltage domains supplied by different voltage level .Usually conventional level shifter which can shift any voltage level signal to a desired higher level with low leakage current .In this level shifter we used multi VDD design techniques which give more design flexibili...

Low-voltage high-speed switched-capacitor (SC) circuit design without using voltage bootstrapper is presented. The basic building block used for low-voltage SC circuit design is the auto-zeroed integrator (AZI), which can work at both low voltage and high sampling frequency. With this method, two low-voltage SC systems were successfully designed and implemented in 1.2m CMOS technology. The firs...
