Abstract
The 3 dB bandwidth of a low-noise amplifier (LNA) is increased by 23% from a range of 1-6.7 GHz to a range of 1-8.25 GHz through digital assist. The LNA has a multi-stage topology and the gate bias voltages are dynamically optimised in real-time to obtain the best gain and noise figure as a function of the signal input frequency.
