ABSTRACT:
A low voltage, low power, wideband quadrature divide-by-three frequency divider using a wideband low voltage, low power differential Muller C element with multiple inputs operates on quadrature input and quadrature output signals. This frequency divider can be used in frequency synthesizers and as quadrature local oscillator generator.
