Abstract
Band pass amplifiers and methods for driving the same are described. According to one embodiment, a frequency selective network is provided in a feedback loop. An analog-to-digital converter is coupled to the frequency selective network. A switching stage is coupled to the analog-to-digital converter for producing a continuous-time output signal. The switching stage includes at least one resonance circuit configured to resonate at a resonance frequency and thereby generate at least a portion of the continuous-time output signal. A continuous-time feedback path continuously senses and feeds back the continuous-time output signal to the frequency selective network.
