Patent ID: 7885625

Claim:
Radio frequency analog to digital converter circuitry comprising: A. a low noise amplifier having an antenna input, a feedback input, and two outputs; B. two transconductance amplifiers, each having two inputs connected with the two outputs of the low noise amplifier and each having an output; C. two quantizers, each having an input connected with the output of a transconductance amplifier and an output; D. a local oscillator providing multiphase clock; E. four flip-flops, each having a logic input, a logic output, and a clock input, the logic inputs of two flip-flops being connected with the output of one quantizer and the logic inputs of the other two flip-flops being connected with the output of the other quantizer, each clock input being connected with one of the multiphase clock signals; and F. an RF feedback engine having four inputs coupled with the four outputs of the flip-flops and an output connected with the feedback input of the low noise amplifier.
