Low-distortion low-voltage operational transconductance amplifier
Introduction: Recent research shows a high demand for highly linear operational transconductance amplifiers (OTAs) with an aim to reduce total harmonic distortion (THD) [1–4]. However, most of these linearisation techniques may present important drawbacks such as reduced effective transconductance and significant power consumption. On the other hand, low power supply and power consumption solut...
متن کاملOperational Transconductance Amplifier for Highly Linear Application
–This paper presents a highly linear Operational Transconductance Amplifier (OTA) that combines two linearization techniques, one with adaptive biasing of differential pairs and second with resistive source degeneration. The Operational Transconductance Amplifier has ±0.9v power supply. Operational Transconductance Amplifier has been simulated with TANNER 0.18μm CMOS technology in Tspice. The s...
متن کاملA Cmos Class-ab Transconductance Amplifier for Switched-capacitor Applications
A novel CMOS operational transconductance amplifier (OTA) is presented, using a fully differential singlestage core OTA as input stage and a differential to single current converter as output stage, each biased at a separate current level. A large gain-bandwidth (GBW) product (2.7 MHz) and a high slew-rate (5 V//.LS) can be obtained by applying a large bias current to the core OTA. Due to the c...
متن کاملProcessing of Communication Signal Using Operational Transconductance Amplifier
This paper proposes a signal processing methodology of communication system and realized that circuits using operational transconductance amplifier (OTA). Two important classes of communication circuit, delta modulator and compander have been designed using that procedure. In the first implementation coded pulse modulation system is demonstrated which employ sampling, quantizing and coding to c...
متن کاملOperational Transconductance Amplifier for Low Frequency Application
This paper presents the design of CMOS operational transconductance amplifiers (OTAs) with very small transconductance (of order of nano ampere per volt), which uses in very low frequency continuous time filters. This design uses current division technique to reduce the transconductance of OTA. This design is simulated in SPICE tool using 0.25μm technology model file.
