In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...

In this paper, feed-forward techniques are revised and used for the design of high-frequency Operational Transconductance Amplifiers (OTA). For the same power consumption and similar transistor dimensions the two-path and three-path folded-cascode OTAs present both smaller settling error and faster response as compared with the typical folded-cascode topology. Also, a No-Capacitor FeedForward (...

Source-drain follower has been designed and implemented for monolithically integrated biosensor array. The circuit acts as a voltage follower, in which a sensing transistor is operated at fixed gatesource and gate-drain voltages. It operates at 10 nW power dissipation. The wide-swing cascode configurations are investigated in constant and non-constant biasing methods. The constant biased cascod...

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...

The goal of internal frequency compensation of a low dropout voltage regulator (LDO) is the selection of a small-value, ESR-independent output capacitor. Cascode compensation formed by a common-gate transistor acting as a current buffer, an optional series resistor, and a compensation capacitor creates a dominant pole and a left-halfplane (LHP) zero, allowing adequate phase margin and stable LD...

Antenna arrays are of perennial interest and relevance to RF wireless system designers, indeed the rise of 5G is showing their importance is only growing. Most implementations of linear arrays use phase shifters to feed the array and hence form the main-lobe beam. In the 1960s, a technique using RF switches and Fourier analysis was discovered to be a viable alternative to phase shifters called ...

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...
