This paper develop a 2.6-GHz receiver RF front-end for 3GPP LTE system. Digital Low-IF technique has been chosen as the receiver architecture. The RF front-end includes differential source inductor degeneration LNA and folded-cascode mixer. Due to the LTE system is applied to portable device, to achieve low power consumption issue, all of the LNA transistors are biased in sub threshold region, which...
This paper presents a low power CMOS RF front-end with a low noise amplifier (LNA) and mixer for long term evolution (LTE) direct conversion receiver. Noise figure and linearity are key parameter of LTE receiver front-end. The source inductive degeneration LNA is designed achieving matched input impedance over a wide bandwidth. For low power consumption issue, a direct conversion receiver with LNA...
