A highly linear Trans-Impedance Amplifier (TIA) for 5G New Radio mobile communication receivers is presented. The TIA has a cut-off frequency programmable from 500 MHz up to 1.5 GHz. The TIA is based on a Feed-Forward compensated amplifier. To ensure stability while achieving high bandwidth and low power, an inductor is used inside the feed-forward stage. A test chip has been realized in 28 nm CMOS technology. The TIA achieves an In-band O1P3 of 32.9 dBm and the output integrated noise from 20 MHz to 1.5 GHz is lower than 300 mu V-rms with a power dissipation of 17 mW.

Abstract
A highly linear Trans-Impedance Amplifier (TIA) for 5G New Radio mobile communication receivers is presented. The TIA has a cut-off frequency programmable from 500 MHz up to 1.5 GHz. The TIA is based on a Feed-Forward compensated amplifier. To ensure stability while achieving high bandwidth and low power, an inductor is used inside the feed-forward stage. A test chip has been realized in 28 nm CMOS technology. The TIA achieves an In-band O1P3 of 32.9 dBm and the output integrated noise from 20 MHz to 1.5 GHz is lower than 300 mu V-rms with a power dissipation of 17 mW.File in questo prodotto:
