Abstract

An infrared receiver with feedforward offset extractor for free-space wireless communications is designed using a standard 0.25 μm CMOS process. An offset extractor is used to cancel the offset voltage without the negative feedback network. It provides a small gain at low frequency and can eliminate the low frequency noise efficiently. The receiver achieves 90 kΩ transimpedance gain and 250 MHz bandwidth with 15 pF photodiode capacitance. The total power consumption is 37.5 mW at 2.5 V supply voltage.
