Abstract:
The disclosure relates to technology for a receiver having a receive signal path including a mixer, a differential fixed gain or variable gain amplifier, and a differential filter. The mixer is configured to receive an RF signal, receive an oscillator signal, and output a differential down converted signal at one of a baseband or intermediate frequency (IF). The amplifier is downstream of the mixer and configured to receive the differential down converted signal from the mixer, apply a gain thereto, and output an amplified differential signal. The filter is downstream of the amplifier and configured filter the amplified differential signal received from the amplifier, and output a filtered differential signal. By locating the differential filter downstream of the differential amplifier within the receive signal path, distortion caused by the mixer is mitigated compared to if the filter were located upstream of the filter.

Claim (Index 11):
A method for use within a receiver, the method comprising:\n using a mixer to mix an RF signal with an oscillator signal to thereby produce a differential down converted signal at one of a baseband or intermediate frequency (IF); using a differential variable gain amplifier (VGA) downstream of the mixer to apply a gain to the differential down converted signal to thereby produce an amplified differential signal, wherein the differential VGA includes a first cross-coupled segment between differential input terminals of the differential VGA and a negative (\u2212) input of signal processing circuitry of the differential VGA, and also includes a second cross-coupled segment between the differential input terminals of the differential VGA and a positive (+) input of the signal processing circuitry of the differential VGA; using a differential filter downstream of the differential VGA to filter the amplified differential signal to thereby produce a filtered differential signal; and adjusting a gain of the differential VGA, while maintaining a substantially consistent frequency response and a substantially constant input impedance of the differential VGA, by adjusting one or more component values of the first and second cross-coupled segments while keeping substantially constant a specified relationship between the component values of the first and second cross-coupled segments; wherein the mixer, the fully differential VGA, and the fully differential filter are each part of a receive signal path of the receiver and are coupled in that sequential order.
