This paper reports an area-efficient LNA design using an active inductor which can be realised in various UHF band receivers. The overall low noise performance of LNA is achieved by cancelling the inductor noise through additional feed forward path. This circuit is implemented using 0.18μm CMOS technology with cadence environment and its operating range is 0.4 to 1GHz. Design is simulated in vi...

An analytical procedure for the calculation of the inductance of planar zig-zag spiral inductors is proposed. The procedure is based on the partial inductance concept and models the inductor as a series of a number of parts. The self-inductance of each individual part, which has the shape of a parallelogram, and the mutual inductance between any two parts of the inductor are determined. The ind...

frequency to retain the triangular shape of the inductor current. It will be assumed in the following, therefore, that.the output signal of amplifier A, includes a remnant of the inductor current triangular waveform (except for possible curvature of the corners) multiplied by a constant (kJ. In CM realisation (Fig. 2), the output of the error amplifier V;, modified by a 'compensation slope' Mc ...

A novel modified space vector pulse width modulation (MSVPWM) strategy for Z-Source inverter is presented. By rearranging the position of shoot-through states, the frequency of inductor current ripple is kept constant. Compared with existing MSVPWM strategies, the proposed approach can reduce the maximum inductor current ripple. So the volume of Z-source network inductor can be designed smaller...

This paper presents a new circuit topology designed to minimise the weight of the control circuit required to actuate multiple piezoelectric actuators. It can independently set the phase and bias voltage on each piezoelectric actuator through the use of a single inductor. This is highly desirable in weight constrained applications such as unmanned aerial vehicles as the ferroelectric material r...

This paper proposes an ultra compact LC-VCO. Due to the speed-up of CMOS digital circuits, jitter of ring oscillators is becoming a critical problem. Even though an LC-VCO has a better phase noise, a layout size of on-chip inductor is a problem as a clock generator. Thus, the proposed LC-VCO consists of a very compact stacked-spiral inductor and active components placed are beneath the inductor...

Abstract: In many power factor correction applications, the power level can reach maximum value and sometimes the input voltage also will be too high. For high power and high voltage applications the inductor volume and weight is the major concern of the conventional boost converter. In this paper the two inductor boost converter is adopted which uses smaller inductors yielding high power densi...

We propose a universal MEMS technology platform for fabricating integrable passive components for radio frequency (RF) integrated circuits. This platform is based on a novel surface-micromachined MicroElevator by Self-Assembly (MESA) techque. Both high-Q inductors and variable capacitors can be realized by the MESA technology. A surface-micromachined spiral inductor that is raised by 250 pm abo...
