A low power 2.4 GHz variable-gain low noise amplifier for wireless applications
A 2.4 GHz variable-gain low noise amplifier (VGLNA) intended for use in a Wide-band Code Division Multiple Access receiver was designed in 0.18 um CMOS process for low voltage and low power applications. Rivaling classical designs using voltage mode approach, this design used the current mode approa...
