Receiver circuits

Abstract

A receiver circuit comprising: an input terminal configured to receive an input-signal; a feedforward-ADC configured to provide a feedforward-digital-signal based on the input-signal; a feedforward-DAC configured to provide a feedforward-analogue-signal based on the feedforward-digital-signal; a feedforward-subtractor configured to provide an error-signal based on the difference between the feedforward-analogue-signal and the input-signal; an error-LNA configured to provide an amplified-error-signal based on the error-signal; an error-ADC configured to provide a digital-amplified-error-signal based on the amplified-error-signal; a mixer configured to down-convert a signal in a signal path between the input terminal and the error-ADC; and an error-cancellation-block configured to provide an error-cancelled-signal based on a difference between the digital-amplified-error-signal and the feedforward-digital-signal.
