Title
Highly linear down-conversion mixer in 65nm CMOS for a high supply voltage of 2.5V
Abstract
A direct down conversion Gilbert-type mixer in combination with an active low-pass filter for 4MHz is presented. The Gilbert-type mixer is enhanced with a source degeneration to improve the linearity performance. The active filter is a linearity enhanced differential amplifier with feedback network. For the high supply voltage of 2.5V additional over-voltage protection with cascodes is added to the circuit parts. The entire receiver part consumes 6.88mA from a 2.5V supply. A high gain of 26.6dB is achieved by the active mixer in combination with the active filter. The noise figure of the entire circuit is only 11.8dB. The input referred intercept point of 3rd-order is +18.6dBm.
