本論文中, 我們實作了ERMES系統中頻解調電路中之混波器、限幅放大器、數位鑑頻器。我們分別使用UMC 0.5微米DPDM、TSMC 0.5微米SPDM以及UMC 0.8微米DPDM三種製程製作晶片。晶片總面積為 0.8675mm/sup 2/。經實驗量測,混波器轉換益為-3.1dB, 限幅放大器之最小輸入電壓為150mV。在3V的電壓操作下, 全部電路的總功率消耗為6.64mW。 In this paper, we have implemented the mixer, the limiting amplifier, the digital frequency discriminator for ERMES pager system. Those circuits have been implemented by UMC 0.5μm DPDM, 0.8μm DPDM, and TSMC 0.6μm SPDM process, respectively. The total chip area is 0.8675mm/sup 2/. The conversion gain of the mixer is -3.1dB. The minimum input voltage of the limiting amplifier is 15mV with the operating frequency of 455KHz. The total power consumption of the mixer, the limiting amplifier, and the discriminator is 6.64mW with 3V supply voltage.
