The realization of matched impedance wide-band amplifiers fabricated by TSMC 0.35μm CMOS process is reported. The technique of multiple-feedback loops was used to achieve terminal impedance matching and wide bandwidth. The experimental results showed that a small signal gain of 12.7dB and a 3-dB bandwidth of 1.7GHz with in-band input/output return loss less than 10dB were obtained. The intrinsic over-damped characteristic of this amplifier was proved and source capacitive peaking was used to remedy this problem. The trade-off between the input impedance matching and bandwidth was also found.
