Abstract:

A field-programmable noise-canceling wide-band receiver front end with high performance LNTAs is presented. The common-source (CS) and common-gate (CG) LNTAs are split into several cells whose bias point can be individually programmed in class AB or C yielding a highly linear hybrid class-AB-C LNTA. The 40nm LP CMOS receiver prototype can be programmed on the fly to adapt to different RF environments; it was tested in a low noise mode, a high linearity mode and a low power mode. Across these modes, the receiver has maximum gain of 53dB, a minimum NF of 2.2dB, a maximum B1 dB of +11dBm, and a maximum OB-IIP3 of +21dBm; the signal path consumes between 15 and 40mA from a 2.5V supply and the LO current varies from 2.2 to 20mA from a 1.1V supply across operating frequencies. The measured LO emission at the antenna port is <;-84dBm.
