This article presented the design of a large drive current laser diode amplifier for 2.4‐GHz radio‐over‐fiber transmission systems in TSMC 0.18‐µm CMOS technology. The proposed drive amplifier adopted a single‐ended two‐stage amplifier structure with the operating voltages of 1.8 and 3.6 V. The technique of dynamic bias is used to enhance linearity. The measurement results show that the linear amplifier achieves the power gain of 16.9 dB, the output 1‐dB compression point of 20.1 dBm at 2.4 GHz. The maximum output modulation current is up to 64 mA. The components are all on chip including the input and output matching network, and the total chip area is 1.0 × 0.73 mm2. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1971–1974, 2014
