Title:
RADIO FREQUENCY LOW NOISE AMPLIFIERS
Document Type and Number:
WIPO Patent Application WO/2021/102477
Kind Code:
A3
Abstract:
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a programmable input impedance circuit for a radio frequency (RF) low noise amplifier (LNA) including a high impedance mode circuit and a low impedance mode circuit. The high impedance mode circuit includes an inductor-degenerated transconductor transistor, an inductor selectively coupled between a source of the inductor-degenerated transconductor transistor and a ground, and a capacitor coupled between a gate of the inductor-degenerated transconductor transistor and the source of the inductor-degenerated transconductor transistor. The low impedance mode circuit includes a shunt resistor selectively coupled between an RF input source and an alternating current (AC) ground.
