技術說明

本發明係一種自我混波接收機及其方法，該接收機係由一高輸入阻抗電壓放大器、一多級放 大器、一混波器及一數位輸出轉換器所構成，該接收機利用該高輸入阻抗電壓放大器及該多 級放大器去接收及放大一電波訊號，接著，藉由該混波器降頻放大後之訊號，再利用該數位 輸出轉換器解調成直流訊號並轉換成一數位訊號；而該接收機之電路架構中，因不需設置任 何電感元件，使該接收機可節省大量的晶片面積以及降低其功率消耗。 This invention is primarily a circuit structure of self-mixing receiver, and the methodology of circuit structure is described as follows. The first stage is a high input impedance voltage amplifier utilized to amplify the received RF carrier signal from the antenna. Besides, there are no any inductors required. The second stage is a multi-stage amplifier to amplify the output signal of first stage to rail-to-rail level, which is quite the same with supply voltage. The third stage is a mixer adopted to lower the signal frequency. The fourth stage is a digital output converter, which is proposed to demodulate the electric signals and convert the demodulated signal to digital signal.
