In this paper several tuning strategies for integrated active filters are discussed. Furthermore we compare two compensation schemes to decrease the temperature dependence of the transconductance value of a differential gain stage. The compensation circuitry consists of on-chip temperature sensors and a level adjustment circuit all realized by standard CMOS transistor techniques. The temperatur...

In this paper, a current-mode Kerwin-Huelsman-Newcomb (KHN) filter structure employing four z-copy current follower transconductance amplifiers (ZC-CFTAs) and two grounded capacitors is proposed. The circuit structure has one low-impedance current input and three high-impedance current outputs and enables realizing lowpass, bandpass and highpass current responses simultaneously. The bandstop an...

© 2009 ETRI Journal, Volume 31, Number 5, October 2009 A novel tunable transconductor is presented. Input transistors operate in the triode region to achieve programmable voltage-to-current conversion. These transistors are kept in the triode region by a novel negative feedback loop which features simplicity, low voltage requirements, and high output resistance. A linearity analysis is carried ...

This chapter is devoted to the realization of some novel active circuits by using transconductance amplifiers. The transconductance amplifier can be realized by the widely used device Op-Amp and specially designed operational transconductance amplifier (OTA). By using single Op-Amp in one circuit itself we can get two filter responses. The first circuit realizes first order low pass – high pass...

The signal to noise ratio and resolution of an analog to digital converter is governed by the linearity constraints of the basic building block, which is the Operational Transconductance Amplifier (OTA). The OTA design is based on MOS transistors that are inherently non linear and lead to performance deterioration. To overcome the non-linearities imposed by the OTA a resistive source degenerati...

The development of transistors with high gain is essential for applications ranging from switching elements and drivers to transducers for chemical and biological sensing. Organic transistors have become well-established based on their distinct advantages, including ease of fabrication, synthetic freedom for chemical functionalization, and the ability to take on unique form factors. These devic...
