Abstract :
A 2.3GHz transimpedance preamplifier designed in a TSMC 0.18μm CMOS technology for optical communication is presented. A wide-swing cascode (WSC) topology provides high transimpedance gain, wide bandwidth, large output voltage swing, low input impedance and low power consumption. The SpectreS simulations show a transimpedance gain of 1.12KΩ (61dBΩ), 3-dB bandwidth of 2.3GHz, low input impedance (<50Ω), dynamic range of 66dB, 650mV output voltage swing and 2.3mW power consumption with 1.5V voltage supply.
