This paper provides a voltage mode (VM) multi input single output (MISO) universal filter with the help of voltage differencing inverting buffer amplifier (VDIBA). All the filter functions i.e., Low pass, band pass, band reject, high pass, and all pass filter functions can be realized without modifying the circuit configuration. The pole frequency can be independently tunable by its transconduc...

The duty-cycle of a clock, within the VLSI IC, is liable to be changed when the clock passes through several buffer stages in the multistage clock buffer design. The pulse-width may be changed due to unbalance of the p and n MOS transistors in the long CMOS buffer. This paper describes a delay locked loop with double edge synchronization mainly used in a clock alignment process. SPICE simulatio...

This article proposed a simple self cascode RGC amplifier configuration to increase the gain and bandwidth. The cascode amplifier eliminates the miller capacitance between input and output and facilitates high gain, high input and output impedance with high bandwidth. However, the cascode amplifier requires relatively high supply voltage for proper operation and it decreases the output voltage ...

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...

Active filters play important role in communication systems. They can be obtained and constructed by different methods. Recently, there is a tendency of designing current-mode circuits using unity-gain active elements such as, CFOAs, CCIIs, etc. instead of classical infinite gain operational amplifiers in active filter design. This paper presents transresistance multifunction filter realization...

This thesis presents the design, analysis, and experimental results of a circuit to be used as a position sensor for microfabricated electric motors. The circuit is designed to measure the capacitance between the rotor blades and sensor electrodes implanted into the substrate beneath the rotor. This capacitance typically varies between five and fifteen femtofarads as the rotor turns. Analytic a...

Novel preamplifiers for working standard photoconductive (PC) and photovoltaic (PV) HgCdTe detectors have been developed to maintain the spectral responsivity scale of the National Institute of Standards and Technology (NIST) in the wavelength range of 5 μm to 20 μm. The linear PC mode preamplifier does not need any compensating source to zero the effect of the detector bias current for the pre...

A D-band divide-by-6 injection-locked frequency divider (ILFD) is presented. The basic mechanism of high division ratios frequency divider is investigated. The circuit employs a wideband microstrip Lange coupler, a microstrip delay line and a pair of Cascode transistors to form a feedback loop for enhanced divide-by-6 operation. The proposed ILFD is fabricated with chip size of 0.7 × 0.9mm2 in ...

The source follower circuit is used as a voltage buffer and level shifter. It is more flexible level shifter as the dc value of voltage level can be adjusted by changing aspect ratio of MOSFETs. It is desired to have low output resistance for such applications. Source follower can give minimum output resistance 1/(gm+gmb) with load resistance and channel resistance tending to infinity. The supe...

This paper presents a low-voltage low-power differential linear transconductor with near rail-to-rail input swing. Based on the current-mirror OTA topology, the proposed transconductor combines the Flipped Voltage Follower (FVF) technique to linearize the transconductor behavior that leads to classAB linear operation and the virtual transistor technique to lower the effective threshold voltages...
