Multiple-phase frequency translated filter
Abstract:
A frequency translation filter includes a baseband filter circuit, a clock generator, and a switching circuit. The baseband filter circuit is operable to provide a baseband filter response. The clock generator is operable to generate multiple-phase clock signals at a desired frequency. The switching circuit is operable to frequency translate the baseband filter response of the baseband filter circuit to a high frequency filter response in accordance with the multiple-phase clock signals.
