A C-gs compensating resistive mixer with low conversion loss at a low LO power level is proposed. In the proposed mixer with an additional transistor, C-gs looking at the gate applying an LO signal is reduced by C-gd, C-gs, and C-ds of the additional transistor. This enables the proposed resistive mixer to have low conversion loss at a low LO power level. This enables the circuit to have high LO-RF isolation and facilitates an RF and IF matching network design. The fabricated chip size using 0.13 mu m CMOS technology is 0.71 x 0.69 mm(2). It achieves a conversion loss of 6.2 to 9.7 dB at an RF frequency of 56 to 63 GHz, and an input P-1dB of -2.5dBm at an LO power of 0dBm. This is believed to be the lowest conversion loss among V-band resistive mixers.
