A 45RFSOI DC to 32 GHz Bandwidth Inductorless low power amplifier

In this work, an ultra-wideband inductorless amplifier implemented in a 45nm CMOS SOI technology is presented. The amplifier operates over a DC to 32 GHz frequency range. The architecture allows a rail-to-rail operation for a supply voltage of 1V. The amplifier achieves 19 dB gain with the input return loss better than -10dB from DC to 12 GHz and output return loss better than -12dB overall bandwidth. The power consumption is 7.8 mW. The core size is only 0.000149 mm

. To the author’s best knowledge, this amplifier provides the highest flat gain over the 32 GHz operation bandwidth and the smallest area compared to similar works in the literature.
