The first offset correction circuit receives a first digital offset correction word and corrects a first offset of the first programmable gain amplifier by adding a first value corresponding to the first digital offset correction word to an input of the first programmable gain amplifier. The second offset correction circuit receives a second digital offset correction word and corrects a second offset of the second programmable gain amplifier by adding a first value corresponding to the second digital offset correction word to an input of the second programmable gain amplifier. A controller measures offsets of the first and second programmable gain amplifiers during a calibration, and provides the first and second offset correction words in response to the offsets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal processor suitable for low intermediate frequency (LIF) or zero intermediate frequency (ZIF) operation","description":"A signal processor for a radio frequency (RF) receiver includes a signal processing path having first and second programmable gain amplifiers and first and second offset correction circuits.
