Patent ID: 7650132

Claim:
A radio receiver formed within an integrated circuit, comprising: a low noise amplifier coupled to receive radio frequency communication signals and to produce amplified radio frequency communication signals to down conversion and oscillation circuitry, the low noise amplifier further comprising: a first group of MOSFETs for receiving and amplifying the RF communication signals; an inductive load coupled to receive power from a power source; a second group of MOSFETs coupled between the inductive load and the first group of MOSFETs; and a third group of MOSFETs coupled in parallel to the series combination of the inductive load and the second group of MOSFETs wherein the transistors of the first, second and third group of MOSFETs are matched and are logically configured so that a number of transistors from the second and third groups of MOSFETs that are biased to be on is equal to the number of transistors in the first group of MOSFETs; and a mixer coupled to receive an amplified output from the low noise amplifier, the mixer for down converting the received amplified output to a baseband frequency.
