Design, fabrication, and test of a 125Mb/s transimpedance amplifier using MOSIS 1.2μm standard digital CMOS process
A front-end transimpedance amplifier for an optical receiver is designed, fabricated through MOSIS 1.2μm digital CMOS foundry, and tested. The amplifier meets the specification of FDDI physical layer. Test shows that the bandwidth of the circuit is more than 100MHz and overall transimpedance gain is about 10,000Ω with 50Ω load resistor. Power dissipation is about 20mW.
