Patent ID: 7392033

Claim:
A radio receiver, comprising: a low noise amplifier (LNA) coupled to amplify a radio frequency (RF) signal to produce an amplified RF signal; down-conversion module operably coupled to convert the RF signal into a low intermediate frequency (IF) signal, wherein the down-conversion module includes: a first mixer to mix the amplified RF signal with an in-phase (I) component of a local oscillation to produce an I component of the low IF signal; a second mixer to mix the amplified RF signal with a quadrature (Q) component of the local oscillation to produce a Q component of the low IF signal; wherein each of the first and second mixers further includes: a first transconductance module having a pair of large signal inputs to receive the I or Q component of the local oscillation; a second transconductance module having a pair of small signal inputs to receive the filtered I or Q components, the second transconductance module coupled to the first transconductance module to mix the I component of the local oscillation with the filtered I components or to mix the Q component of the local oscillation with the filtered Q components; and at least one auxiliary current module coupled to provide a current to the second transconductance module during switching of at least a portion of the first transconductance module; filtering/gain module operably coupled to filter and amplify the I and Q components of the low IF signal to produce a filtered low IF signal; and digital receiver processing module coupled to convert the filtered low IF signal into inbound data.
