The definition of the current conveyor is presented and it is shown how different generations of current conveyors can all be combined into a single definition of a multiple-output second generation current conveyor (CCII). Next, noise sources are introduced into the model, and a general noise model for the current conveyor is established. This model is used for the analysis of selected example...

In this paper a high speed hybrid current mode sense amplifier is presented. Sense amplifier is the most important component of SRAM cell used to sense stored data. Sense amplifiers are used to read the contents of SRAM cells. Sense amplifiers perform amplification, delay reduction and power reduction. Earlier voltage mode sense amplifiers are used to sense the data from bitlines. But with incr...

In this paper we present an ultra low-voltage (ULV) floating-gate (FG) transconductance amplifier The amplifier can operate at supply voltages below 1V in a standard digital double poly CMOS process . The amplifier consists of a sinh shaped output current transconductance amplifier and a tanh shaped transconductance amplifier.

A complementary bipolar low-power, high-speed, current-feedback operational amplifier is described. The amplifier incorporates a new Class AB output stage that enables high output current drive of 100 mA and large voltage swing within 1 V of the supply rails while operating at low quiescent current of 1.5 mA. The amplifier was fabricated in a junction-isolated complementary bipolar process with...

This paper presents a capacitor-less low drop-out (LDO) regulator with current mode transconductance amplifier & slew-rate enhancement circuit. The proposed current mode transconductance amplifier as error amplifier improves the slew rate & slewrate enhancement circuit further senses the transient voltage at the output of the LDO to increase the bias current of the error amplifier for a short d...

Abstract. This paper proposes admittance matrix models to approach the behavior of six modern multiport functional blocks called: differential difference amplifier, differential difference operational floating amplifier, differential difference operational mirror amplifier, differential difference current conveyor, current backward transconductance amplifier and current differencing transconduc...
