Abstract :
This letter proposes a novel up-conversion mixer with pseudo-differential and current-reused topology in 90 nm CMOS technology. The proposed source-pumped up-conversion mixer can operate at near weak inversion under a power consumption of 149 μW from a 0.4 V supply voltage while maintains acceptable circuit performance at millimeter-wave (MMW) frequencies. Measurement results show that the up-conversion mixer exhibits a -0.62 dB conversion gain (CG) and a -4 dBm OIP3. An achieved figure-of-merit (FoM) is 1.46.
