Abstract :
An integrated fully differential CMOS transimpedance amplifier (TIA) with buried double junction photodiode input is described. The TIA features a variable high transimpedance gain (250 kΩ to 2.5 MΩ), large DC photocurrent rejection capability (>55 dB) and low input referred noise density at 100 kHz (2pA/√Hz).
