Abstract: A receiver, such as a television tuner, includes a radio frequency (RF) filter circuit. The RF filter circuit includes a filter, a first node, and a second node coupled to the filter, and a conversion signal path having an input coupled to the first node and an output coupled to the second node, the conversion signal path having an active mixer coupled between the first node and the second node. The active mixer can include, for example, a first transconductor and a first mixer coupled in series between the first node and the second node. The RF filter circuit further includes a feedback signal path having an input coupled to the second node and an output coupled to the first node, the feedback signal path including a second transconductor and a second mixer coupled in series between the second node and the first node.

Abstract: A direct conversion satellite tuner is fully integrated on a common substrate. The integrated tuner receives an RF signal having a plurality of channels and down-converts a selected channel directly to baseband for further processing. The integrated tuner includes on-chip local oscillator generation, tunable baseband filters, and DC Offset cancellation. The integrated tuner can be implemented in a completely differential I/Q configuration for improved electrical performance. The entire direct conversion satellite tuner can be fabricated on a single semiconductor substrate using standard CMOS processing, with minimal off-chip components. The tuner configuration described herein is not limited to processing TV signals, and can be utilized to down-convert other RF signals to an IF frequency or baseband.
