RECEIVER FILTERING DEVICES, SYSTEMS, AND METHODS

摘要

Exemplary embodiments of the invention disclose receiver baseband filtering. In an exemplary embodiment, the filter device (204) may comprise a continuous - time filter and a discrete - time filter operably coupled to the continuous time-filter. The discrete - time filter (204) may include a passive infinite impulse response filter (212) operably coupled between the continuous - time filter and an amplifier. The discrete - time filter may also include an active infinite impulse response filter (218) operably coupled between an output of the amplifier (216) and an input of the amplifier (216). The discrete - time filter (204) may be configured to combine an output of the active infinite impulse response filter (218) and an output of the passive infinite impulse response filter (212) to form a composite signal. Furthermore, the amplifier (216) may be configured to receive and amplify the composite signal.
