- Abstract
- A 2.5 Gb/s CMOS burst-mode transimpedance amplifier (BM-TIA) with a novel peak detection circuit is designed in this paper. The proposed peak detection circuit changes quickly the gain mode of the BM-TIA and then improves the data transmission capacity of the PON system with low power consumption. In order to obtain quick response time of the BM-TIA, a RC-LPF, an amplifier followed it and a replica circuit of the amplifier are built in. This BM-TIA was fabricated in 1P6M 0.18 μm CMOS process. The designed IC exhibits a quick response of 11 nsec for a 2.5 Gb/s burst preamble input. In this condition, this chip of 4 channel consumes 195.4 mW from a 1.8 V supply. In high gain mode, the BM-TIA achieves a gain of 66 dB with 2.45 GHz bandwidth and the eye jitter (rms) of 4.243 ps.
