We describe a fully differential amplifier for oversampled A/D converter applications. This amplifier employs a single stage telescopic architecture using both N-type and P-type gain-boosting technique with capacitive feedback. This architecture offers extremely high gain, low noise, low power and the need for compensation. But the potential slow-settling problem due to the slow doublet should ...

We propose capacitively driven low-swing global interconnect circuit using a receiver that utilizes magnetoelectric (ME) effect induced magnetization switching to reduce the energy consumption. Capacitively driven wire has recently been shown to be effective in improving the performance of global interconnects. Such techniques can reduce the signal swing in the interconnect by using a capacitiv...

In this paper a current mode very low voltage (LV) (1 V) and low power (LP) (21 μW) differential difference second generation current conveyor (CCII) is presented. The circuit is developed by applying the current sensing technique to a fully balanced version of a differential difference amplifier (DDA) so to design a suitable LV LP integrated version of the so-called differential difference CCI...

This paper describes the design of a fully differential CMOS amplifier for clipping control circuit. The amplifier with specification of low settling time less than 5ns, high dynamic range above 90dB and low power supply of 3 volt is designed and realized in a 0.35 μm CMOS process with 3 volt power supply. Simulation confirm the presented design.

This paper describes a 1GHz differential to single-ended amplifier for instrumentation. The unity gain amplifier can directly drive a 50Ω load with a common-mode voltage centered at ground and can accept up to a 1 VP-P input signal. The measured noise floor is below 20nV/√Hz for most of the bandwidth and the common-mode rejection is 20dB at 1GHz.

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...

The design of a fully differential CMOS transconductance operational amplifier is presented. Topology selection, compensation, biasing, and common mode feedback are discussed. Design analysis and simulations are presented demonstrating that the amplifier exceeds the specifications for application in the first stage of a 13-bit pipelined A/D converter, while dissipating an average of 66 mW of po...

A low-voltage differential version of a high performance voltage follower is presented. The proposed circuit is very compact, and symmetric with respect to the input devices. Both differential input devices are enhanced by local shunt feedback, increasing the gain and, thus, reducing the output resistance for higher precision. The circuit has proved useful as a winner-take-all (WTA) circuit. It...
