Low-voltage analog circuits based on wideband capacitive coupling
A technique for wideband low-voltage analog circuit operation based on capacitive signal coupling is discussed. Circuits based on this technique do not show the GB degradation of other low-voltage approaches based on floating-gate transistors. The technique is validated with simulations of a new CMOS mixer and experimental results of a test chip in a 0.5 mum CMOS technology.
