Patent ID: 8045943

Claim:
A radio frequency receiver, comprising: a low noise transconductance amplifier operable to amplify and convert a received voltage of a radio frequency signal to a first current; a pulse generator operable to generate pulses from a periodic signal, the pulses having a duty cycle of 35% or less; a crossover correction circuit to reduce overlap of the pulses; a double balanced mixer operable to combine the first current with the pulses to produce a second current, the second current comprising an intermediate frequency signal; and a direct coupled complex filter operable to filter the second current to a filtered analog signal; where the crossover correction circuit is operable to control a crossover threshold of the pulses and where: the pulses comprise in-phase pulses and quadrature pulses; the crossover threshold comprises a crossing point of an amplitude of the in-phase pulses and the quadrature pulses, the crossing point selected to reduce the amount of time the in-phase pulses and quadrature pulses are simultaneously active; and the intermediate frequency signal comprises an in-phase signal and a quadrature signal.
