Abstract
A local oscillator (LO) buffer circuit comprises first and second LO buffers arranged in a cross coupled configuration. The first LO buffer generates in-phase output signals in response to in-phase input signals, and quadrature output signals from the second LO buffer. The second LO buffer generates the quadrature output signals in response to quadrature input signals and the in-phase output signals. The LO buffers may include inductive loads. The LO buffers may include MOS transistors or bipolar junction transistors.
