In order to realize the \nportable electric devices, the miniaturization, light weight and low cost of the devices are very important issues, \nand longer life of the battery is also desired. The implementation of RF analog circuits and the baseband \ndigital circuits in the same chip by using CMOS technology leads to the capability of reducing the size, weight, \ncost and power. However, the implementation is very difficult because RF CMOS circuit technology cannot be \nestablished.\nIn this paper, the optimal design to improve the conversion gain of the even-harmonic mixer used in the direct \nconversion receivers is proposed. The RF signal input terminal of MOSFET's transconductance parameter(K) \nis not changed in consideration of the influence of parasitic capacitance in the imput terminal, but the LO \nsignal input terminal is changed. Under these conditions, the optimal value could be derived. The proposed \ncircuit that used the optimal value was evaluated by using HSPICE-RF. The results show that the operation \nof the circuit as an even-harmonic mixer is confirmed. Furthermore, the conversion gain to the baseband of the \nproposed circuit can be improved by 4 dB as deriving the theory. The circuit using the optimal value is very \nuseful for high- gain even-harmonic mixers.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty
