Abstract
Semiconductor technology scaling has enabled function density
increases and cost reductions by orders of magnitudes, but for
shrinking device sizes the operating voltages have to be reduced.
As we move into the nanoscale semiconductor technologies, power
supply voltages well below 1 V are projected. The design of MOS
analog circuits operating from a power supply voltage of 0.5 V is
discussed in this paper. The scaling of traditional circuit topolo-
gies is not possible anymore and new circuit topologies and bias-
ing strategies have to developed. Several design examples are pre-
sented. The circuit implementations of gate and body-input 0.5 V
operational transconductance amplifiers and their robust biasing
are discussed. These building blocks are combined for the realiza-
tion of active varactor-tuned RC filters operating from 0.5 V using
standard devices with a |VT| of 0.5V in a standard 0.18 µm CMOS
technology.
