Abstract
In recent years, the world of wireless communications has been changing very rapidly. In order to realize the
pocket electric device, the reduction in the miniaturization as apparatus, lightweightizing, and cost is important,
and also battery operation covering a long time is called for. The wireless communication devices need RF analog
circuits such as mixer. In CMOS technology, if it successfully merges RF analog and baseband digital blocks,
it is possible to reduce size, weight, cost and power consumption. In this paper, a low-supply-voltage and the
even-hamonic mixer using the LCtank which paid its attention to the conversion gain is proposed. The proposed
multiplier has advantages of the secondary distortion ingredient dose not occur and low noise.
Simulations of the multiplier demonstrate the conversion gain of -13.1 dB, the THD of 0.145 % and the S/N
ratio of 141.65 dB with VDD=1.5 V.
