The design of a 2.4GHz radio-over-fiber (ROF) laser diode drive amplifier using TSMC 0.18-um CMOS technology is presented in this paper. The proposed drive amplifier is a single-ended two-stage amplifier with the operating voltages of 1.8V and 3.3V. The technique of dynamic bias is employed to enhance linearity. The post simulation results show that the linear amplifier achieves the power gain of 26.26dB, the output 1dB compression point of 20.49dBm at 2.4GHz. The maximum power added efficiency (PAE) is 27.97%. The components are all on chip including the input and output matching network, and the die size is 1.065mm×0.73mm.

The design of an analog laser diode (LD) driver for 5GHz radio-over-fiber (ROF) transmission systems is presented in this paper. The proposed linear LD driver adopted a single-ended two-stage amplifier structure with the operating voltages of 1.8V and 3.3V respectively. The technique of self-biased cascade amplifier is employed to increase the gain and alleviate the danger of gate oxide breakdown. The simulation results show that the analog amplifier achieves the power gain of 35dB and the output 1dB compression point of 18dBm at 5GHz. The corresponding output modulation current is up to 50mA at the 1dB compression point. The total chip area is only 710μm×580μm with the all on chip input and output matching network, and the power consumption is 130mW.
