半波和全波精確度整流器使用OTA
The half-wave and the full-wave precision rectifier using OTA
摘要
使用OTA來設計全波和半波整流器，論文中將介紹OTAs（ Operational Transconductance Amplifiers）電流式類比積體電路主動元件的特性、並設計建立運算轉導放大器（OTA）元件電路模型結構，接著使用TSMC 0.35µm CMOS製程中的N-MOSFET和P-MOSFET 架構出一顆OTA元件，並將此OTA元件串聯上整流器單元，經整流單元，形成電流輸出波形，再經輸出電阻RL，將其電流波形轉換為電壓輸出波型之設計。 在此論文中使用一顆OTA，可產生正半波和負半波輸出。使用二顆OTA，可產生正全波和負全波輸出。在全波整流方面可利用最後介紹BOTA（Bidirectional Operational Transconductance Amplifier）來表示全波整流電路之等效電路。 在此整流器中所使用的二極體，亦使用TSMC 0.35µm CMOS製程中的二極體元件來建立，在實驗中將全程使用H-spice來模擬驗證輸出波形理論。

The thesis is to discuss with the design of precision full-wave and half-wave rectifiers using OTAs（ Operation Transconductance Amplifiers ）. This paper will introduce the characteristic of the active OTA current-mode analog integrated circuit, and discuss the marking of OTA’s circuit structure. The OTA is designed by N-MOSFET and P-MOSFET of TSMC 0.35μm CMOS technology. Then, the output of the OTA is connected to the rectifier, thus forming rectified current waveform at the output of the rectifier. Then, through the output resistor RL, the current waveform is transformed into voltage waveform. In this paper, the design of positive and negative half-wave rectifier uses one OTA, and the design of positive and negative full-wave rectifier uses two OTAs. In the design of the full-wave rectifier, BOTA ( Bidirectional Operational Transconductance Amplifier ) can also be used to represent the equivalent circuit of such rectifier. The diodes used by the full-wave and half-wave rectifier also belongs to TSMC 0.35μm CMOS technology. Throughout the experiment, the H-spice is used to simulate the output waveform to confirm the waveform theory.
