Key words operational amplifers , gain - bandwidth product , circuit - mode , active filter 關(guān)鍵詞運(yùn)算放大器,帶寬增益積,電流型,有源濾波器
It does not need any matched components to reach high cmrr and its bandwidth is not gain - bandwidth product limited 該結(jié)構(gòu)不需要任何精確匹配的電阻就能達(dá)到高的共模抑制比,并且其帶寬不受帶寬增益積的限制。
Chirp signal is a kind of pulse - compressed signal with large time - bandwidth products achieved through linear frequency modulation . it has high resolution in range because of its great bandwidth 線性調(diào)頻信號(hào)是通過(guò)線性頻率調(diào)制獲得大的時(shí)寬帶寬積的一種脈沖壓縮信號(hào),具有大的帶寬,因此有高的距離分辨力。
