A low-power wideband transimpedance amplifier in 0.13µm CMOS

This paper presents a low-power wideband transimpedance amplifier (TIA) for the applications of multi-band wireless communication systems. Realized in a standard 0.13μm CMOS technology, the measured results of the TIA demonstrate the maximum gain of 16dB in the frequency range of 800MHz~4.3GHz, the noise figure of <; 5.88dB, the input-referred third order intercept point (IIP3) of -5.4dBm at 2.4GHz, and the power consumption of 12mW from a single 1.2V supply. The chip occupies the total area of 0.7×1.1mm
