Dalam surat ini elemen aktif baharu, Penguat Transkonduktans Pengikut Semasa (CFTA) untuk merealisasikan blok analog mod semasa dibentangkan. Elemen tersebut ialah gabungan Pengikut Semasa (CF) dan Penguat Transkonduktans Output Seimbang (BOTA). Kemungkinan struktur dalaman CFTA dibentangkan. Penggunaan elemen aktif baharu ditunjukkan pada reka bentuk struktur Kerwin-Huelsman-Newcomb (KHN) yang berfungsi dalam mod semasa. Penapis frekuensi menggunakan elemen CFTA telah direka bentuk menggunakan graf aliran isyarat. Struktur litar menggunakan tiga elemen CFTA dan dua elemen pasif dibumikan. Penapis membolehkan merealisasikan bukan sahaja fungsi asas sebagai penapis rendah (LP), jalur (BP) dan laluan tinggi (HP) tetapi juga penapis takuk dan lulus semua (AP). Kelebihan struktur yang dibentangkan ialah keluaran penapis berada pada impedans tinggi dan oleh itu tidak perlu menggunakan unsur aktif tambahan yang lain. Sifat penapis yang dicadangkan telah disahkan oleh sensitiviti dan analisis AC dalam program PSPICE.

Abstract: In this letter a new active element the Current Follower Transconductance Amplifier (CFTA) for the realization of the current-mode analog blocks is presented. The element is a combination of the Current Follower (CF) and the Balanced Output Transconductance Amplifier (BOTA). Possible internal structure of the CFTA is presented. The usage of the new active element is shown on the design of the Kerwin-Huelsman-Newcomb (KHN) structure working in the current mode. The frequency filter using the CFTA elements has been designed using the signal-flow graphs. The circuit structure employs three CFTA elements and two grounded passive elements. The filter enables realizing not only the basic functions as the low- (LP), band- (BP) and high-pass (HP) but also the notch and all-pass (AP) filter. The advantage of the structure presented is that the outputs of the filter are at high impedance and hence it is not necessary to use other auxiliary active elements. The properties of the filter proposed were verified by sensitivity and AC analyses in the PSPICE program.
