Abstract:
A receiver (300) comprises an antenna input (301), a filter (302), a voltage-to-current converter (303), a down frequency conversion mixer (304), and a current-to-voltage converter (305). The antenna input operably couples to an antenna. The filter has a filter input that operably couples to the antenna input and can further have a filter output. The voltage-to-current converter has an input that is operably coupled to the filter output and can further have a voltage-to-current converter output. The down frequency conversion mixer has a mixer input that is operably coupled to the voltage-to-current converter output and can further have a mixer output. And the current-to-voltage converter has an input that is operably coupled to the mixer output and can further have a current-to-voltage converter output. By one approach, this current-to-voltage converter comprises an amplifier having a current gain of substantially unity or less.
