In this paper, a low Power, Gain Boosted Recycling Folded Cascode Operational Transconductance Amplifier (GB-RFC OTA) is described. The proposed GB-RFC OTA is designed using 130nm CMOS technology and achieves enhanced gain, unity gain bandwidth and slew rate with the low Power budget. The proposed circuit operates on 1V supply voltage and 200 μA bias current and consumes a power of 798μW.The GB...

First, we create a MOS-NDR (negative differential resistance) cell and then put two MOS-NDR cells in cascode (totem-pole) structure. With MOBILE (monostable-bistable transition logic element) theorem we can built a MOS-NDR inverter by placing a NMOS in parallel with the lower part of the cascode structure. The MOS-NDR inverter cascades two Common-Source amplifier and feedback to MOS-NDR inverte...

Low voltage (LV) analog circuit design techniques are addressed in this tutorial. In particular, (i) technology considerations; (ii) transistor model capable to provide performance and power tradeoffs; (iii) low voltage implementation techniques capable to reduce the power supply requirements, such as bulk-driven, floating-gate, and self-cascode MOSFETs; (iv) basic LV building blocks; (v) multi...

This paper presents a new common-mode stabilization method for a CMOS differential cascode Class-E power amplifier with LCtank based driver stage. The stabilization method is based on the identification of the poles and zeros of the closed-loop transfer function at a critical node. By adding a series resistor at the common-gate node of the cascode transistor, the right-half-plane poles are move...

A fully-differential seventh-order 0.05° equiripple linear phase low-pass filter based on multiple loop feedback (MLF) leapfrog (LF) topology is presented for read/write channels. The filter is designed and simulated with the proposed fully balanced, highly linear operational transconductance amplifier (OTA). This OTA contains two complementary differential cross-coupled input pairs and a pair ...

Abstract—This work presents a fully differential CMOS amplifier consisting of two self-biased gain boosted inverter stages, that provides an alternative to the power hungry operational amplifier. The selfbiasing avoids the use of external biasing circuitry, thus reduces the die area, design efforts, and power consumption. In the present work, regulated cascode technique has been employed for ga...

A modification of the conventional Flipped Voltage Follower (FVF) to enhance its output resistance is presented. It consists of replacing the conventional cascoding transistor of the basic cell by a regulated cascode scheme. This decreases the output resistance by a factor gmro approximately, the gain of a transistor as an amplifying stage. This is achieved with only two additional transistors ...

Organic transistor technology holds great promise for creating a conformal, human-safe electronic neural interface. These interfaces must amplify the low, microvolt-range brain signals so they can be utilized in analog and digital applications. Brain signals from sensors must be relayed to the transistor’s gate through the dielectric and semiconductor layers, as well as through an encapsulant w...
