In this paper, design of a CMOS tunable versatile filter using current conveyor (CC) is presented. The filter is realized at the same time as on the chip is tunable for low pass, band pass, high pass, and elliptical notch filter. The circuit is utilizes two current conveyors, one Operational Trans-conductance Amplifier (OTA), four resistors and two grounded capacitors, ideal for integration. It...

A high-linearity and high-speed current-mode sampleand-hold circuit is designed and simulated using a 0.25μm CMOS technology. This circuit design is based on low voltage and it utilizes a fully differential circuit. Due to the use of only two switches the switch related noise has been reduced. Signal dependent -error is completely eliminated by a new zero voltage switching technique. The circui...

The design of a new single stage class AB operational amplifier is presented. Amplifier incorporates an input differential pair with minimum current selector and common-mode feedback to control the tail current. It shows small-signal behavior of a simple OTA, while class AB feedback provides high slew rate when large input signals are applied. Prototype circuit was manufactured in 2pm analog CM...

Studies on new passive elements with memory properties such as memristor, meminductor, and memcapacitor have increased recently. In this article, an operational transconductance amplifier (OTA) based meminductor simulator circuit without using a which is suitable for the physically produced memristor structure, has charge control, floating characteristics can be controlled electronically, propo...

This paper presents a low-voltage nano-power multiple-input operational transconductance amplifier (MI-OTA) with high linearity performance and increased input voltage swing. The enhanced performances are achieved thanks to employing several techniques as the bulk-driven, source-degeneration, self-cascode negative conductance along concept of signal attenuation formed by MOS transistor. MI-OTA ...

The integrated circuit design of a switched-capacitor filter for Bluetooth specifications is described. It was based on the optimum allocation of poles and zeros to generate a transfer function with unequal numerator and denominator orders, so that a direct-form structure with reduced number of opamps and low sensitivity to capacitor ratio errors were obtained. It was designed for implementatio...

A switch-embedded opamp-sharing multiplying digital-to-analogue converter (MDAC) with dual-input-differential-pair operational transconductance amplifier (OTA) is proposed to eliminate the non-resetting and successive-stage crosstalk problems in the conventional opampsharing technique. A 10-bit 80 MS/s pipelined analogue-to-digital converter (ADC) is implemented in a 0.18 mm CMOS process by usi...
