|Abstract: ||Described herein is a power-efficient Gm-C filter, wherein the Gm-C
filter includes several operational transconductance amplifiers (OTAs).
In an example, at least two of the OTAs share a common bias current.
Further, output of one of the OTAs is used to bias another one of the
OTAs. Also described herein is a power-efficient clock generator circuit
that is configured to output non-overlapping clock signals. The clock
generator circuit includes a ring oscillator circuit, which includes
several inverter stages. The clock generator circuit is well-suited for
controlling operation of switches.
