Patent ID: 8126422

Claim:
A receiver comprising: an antenna input configured and arranged to operably couple to an antenna; a filter having a filter input operably coupled to the antenna input and a filter output; a voltage-to-current converter having an input operably coupled to the filter output and a voltage-to-current converter output; a down frequency conversion mixer having a mixer input operably coupled to the voltage-to-current converter output and a mixer output; a current-to-voltage converter having an input operably coupled to the mixer output and a current-to-voltage converter output, wherein the current-to-voltage converter comprises an amplifier having a current gain of substantially unity or less; an integrator operably coupled to the current-to-voltage converter output, wherein the integrator includes an output that is operably coupled via a feedback path to provide a feedback signal to a terminal of the current-to-voltage converter, wherein the integrator includes an amplifier.
