Dalam makalah ini, teknik linearisasi baharu untuk OTA bipolar voltan rendah menggunakan litar fungsi hiperbolik diterangkan. Pertama, reka bentuk litar undang-undang eksponen, yang merupakan blok binaan asas untuk menyusun litar sinus hiperbolik dan kosinus hiperbolik, dicadangkan. Litar ini lebih mudah daripada litar konvensional dan sesuai untuk aplikasi voltan rendah. Seterusnya, dua OTA linear menggunakan litar fungsi hiperbolik dibentangkan. Transkonduktansi diberikan oleh penghampiran rata maksimum. Walaupun reka bentuk OTA berbeza, arus keluaran diberikan oleh ungkapan yang sama. Akhir sekali, prestasi OTA dibincangkan. Julat voltan input linear bagi OTA yang dicadangkan adalah hampir sama dengan OTA konvensional. Walau bagaimanapun, salah satu daripada OTA yang dicadangkan mempunyai tidak lebih daripada dua pertiga pelesapan kuasa yang konvensional. Yang lain mempunyai ciri frekuensi tinggi yang unggul.

Abstract: In this paper, new linearization techniques for low-voltage bipolar OTAs using hyperbolic function circuits are described. First, a design of an exponential-law circuit, which is a basic building block to compose hyperbolic sine and hyperbolic cosine circuits, is proposed. This circuit is simpler than the conventional circuit and is suitable for low-voltage application. Next, two linearized OTAs using the hyperbolic function circuits are presented. The transconductance is given by maximally flat approximation. Although designs of the OTAs are different, the output currents are given by the same expression. Finally, performance of the OTAs is discussed. The linear input voltage range of the proposed OTAs is almost the same as that of the conventional OTA. However, one of the proposed OTA has no more than two-thirds the power dissipation of the conventional one. The other has a superior high-frequency characteristic.
