A 1.227 GHz low power single-ended input, differential output low noise amplifier (balun LNA) for GPS is proposed. A two stage structure with current-reused technique is adopted to achieve low power, low noise factor and high voltage gain simultaneously. The LNA is fabricated in 0.18 mm CMOS process, consuming only 2 mA current from a 1.8 V supply. The LNA is measured to exhibit a differential ...

Class AB differential amplifiers using composite BiCMOS and bipolar transistors are introduced. Their utilization for the implementation of low voltage (+-1.65V) operational amplifiers with high slew rate and rail to rail common mode input voltage range is discussed.

Abstract: A 1 V operating fully differential OTA is presented. We designed a 1 V operating fully differential OTA using NMOS inverters in place of traditional differential pair. To obtain high voltage gain, a two stage configuration has been used in which the first stage has feedforward to cancel common-mode signal and the second stage has commonmode feedback. This OTA was fabricated by 0.18 μm...

Abstract— FinFet is evolved to overcome Moore's law limitations in nanometer regime. Transconductance circuit produces differential output currents, when differential input voltages are applied. A simple FinFet transconductance circuit structure modified from traditional MOSFET is proposed to preserve both area and power. The proposed design contributes a transconductance gain of 5.247 mA/v for...

We certify that this work has passed the scholastic standards requested by the Information and Communications University as a thesis for the Abstract The commercialization of Ultra-WideBand (UWB) ranging from 3.1-10.6 GHz by Federal Communication Commission (FCC) has recently emerged as a promising technology for short-range wireless data communications. The applications of wireless data commun...

The LT®6600-20 combines a fully differential amplifi er with a 4th order 20MHz lowpass fi lter approximating a Chebyshev frequency response. Most differential amplifi ers require many precision external components to tailor gain and bandwidth. In contrast, with the LT6600-20, two external resistors program differential gain, and the fi lter’s 20MHz cutoff frequency and passband ripple are inter...

This paper presents two low-power voltagemode multifunction biquadratic filters using differential difference current conveyors. Each proposed circuit employs three differential difference current conveyors, two grounded capacitors and two grounded resistors. The low-voltage ultra-low-power differential difference current conveyor is used to provide low-power consumption of the proposed filters...

This paper presents a rail-to-rail constant-gm operational amplifier input stage. The proposed circuit changes the tail current of the input differential pairs dynamically for a constant-gm by using dummy input differential pairs. The problem which causes total gm variation is input pairs and dummy input pairs can not take effect at the same time with the common-mode input voltage changes, beca...

Abstract: Due to the expansion of high voltage Alternating Current (AC) power transmission lines and cathodically protected buried pipelines, it is becoming more and more difficult to construct them with enough safe distances between them. Thus, the pipelines are frequently exposed to induced AC interferences, which result in perturbation of Cathodic Protection (CP) due to AC corrosion. To s...

In this paper we promote the Ultra Low Voltage (ULV) NAND gate to replace either partly or entirely the encryption block of a design to withstand power analysis attack.
