Kurzfassung englisch:
A three-stage transimpedance amplifier (TIA) as preamplifier for optical receivers in passive optical networks (PON) designed in a digital 120nm CMOS technology with a supply voltage of 1.5V is presented. An external ternary pin photodiode with a responsivity of 0.85A/W and a capacitance of 1.2pF is used to detect the 1.3μm light being used for upstream in PON. The open-loop gain of the transimpedance amplifier can be varied by a factor of 115 to enable various transimpedances for a wide input-current range without stability problems. Sensitivities of -31.3dBm at 622Mb/s and -28.6dBm at 1.25Gb/s with a bit error ratio (BER) of 10-10 and a pseudo random bit stream (PRBS) of 231-1 are achieved. A wide dynamic optical input power range of more than 27dB can be processed.
