AbstractThis paper deals with the design and analysis of folded cascode operational transconductance amplifier in different regions of operations: strong, weak and moderate inversion region. The folded cascode OTA consists of cascode OTA and cascode gain boosting technique. By using 0.35μm technology, the simulation shows DC gain of 78.42dB with a unity gain bandwidth of 446.07 MHz and power co...

In the literature, Improved Recycling Folded Cascode (IRFC) Operational Transconductance Amplifier (OTA) is proposed for enhancing the DC gain and the Unity Gain Bandwidth (UGB) of the Recycling Folded Cascode (RFC) OTA. In this paper, an enhanced IRFC (EIRFC) OTA which uses positive feedback at the cascode node is proposed for enhancing the differential mode (DM) gain without changing the unit...

In this work, a Physically Unclonable Function (PUF) based on an improved regulated cascode current mirror (IRCCM) is presented. The proposed IRCCM improves the loop-gain of gain-boosting branch over conventional RCCM PUF, thereby increasing output resistance and amplifying mismatches due to random variations. introduction explicit reference in biasing results lower native unstable bits, good r...

An optimum OTA topology is done in order to optimize MOS transistor sizing.Also, the design of folded cascode OTA, which works for frequencies that lead to a base band circuit design for RF application, is based on transistor sizing methodology. Simulation results are performed using SPICE software and BSIM3V3 model for CMOS 0.18μm process, show that the designed folded cascode OTA has a 52dB D...

This paper presents a balanced receiver structure suitable for wireless infrared data communications. The receiver provides a fixed photodiode bias voltage with the use of a regulated cascode input stage. Together with an active feedback loop used to eliminate dc photocurrents, the receiver implements ac coupling without the need for matching capacitors. Differential sensing of the photodiode c...

A fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented here. High gain pseudo-differential auxiliary amplifiers are used to implement the in order boost output impedance of open-loop op-amp. Both stages operate class AB mode.
