This paper introduces several techniques for achieving RF and analog CMOS circuits for wireless communication systems under ultra-low-voltage supply, such as 0.5V. Forward body biasing and inverter-based circuit techniques were applied in the design of a feedforward Δ-Σ A/D modulator operating with a 0.5V supply. Transformer utilization is also presented as an inductor area reduction technique. In addition, application of stochastic resonance to A/D conversion is discussed as a future technology.
