The structure of the miniature three–dimensional (3-D) inductor is presented in this paper. The proposed miniature 3-D inductors have been fabricated in a standard digital 0.35m one-poly-four-metal (1P4M) CMOS process. According to the measurement results, the self-resonance frequency SR of the proposed miniature 3-D inductor is 34% higher than the conventional stacked inductor. Moreover, the p...

A high Q-factor (quality-factor) spiral inductor fabricated by the CMOS (complementary metal oxide semiconductor) process and a post-process was investigated. The spiral inductor is manufactured on a silicon substrate. A post-process is used to remove the underlying silicon substrate in order to reduce the substrate loss and to enhance the Q-factor of the inductor. The post-process adopts RIE (...

A novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm CMOS technology. A resistive-capacitive feedback is used to extend the bandwidth of the amplifier. As the structure is inductor less, it is suitable for low cost integrated optical interconnects. In this paper Improved Particle Swarm Optimization have applied to determine optimal trans-resistance and noise of propose...

This paper presents a simple and efficient interface circuit for electrostatic energy harvesting devices, which uses neither controlled electronic switch nor inductor. A built-in voltage multiplier enables to get bias voltages higher than the circuit output voltage, resulting in an increased power output. This interface circuit was implemented using off-the-shelf components. Its operation was v...

A striped inductor and its utilization of a voltagecontrolled oscillator (VCO) are studied with the aim of suppressing phase noise degradation in Kand Ka-bands. The proposed striped inductor exhibits reduced series resistance in the high frequency region by increasing the cross-sectional peripheral length, as with the Litz wire, and the VCO of the striped inductor simultaneously exhibits a lowe...

The improvement of a conventional Gyrator-C active inductor consisting of common-emitter configured and common-collector configured with resistance feedback is presented. The fixed passive resistor is replaced with tunable active resistor (TAR) to enhance the adjustability of the active inductor. Multi-regulated Cascode (MRC) circuit is applied to boost quality factor Q. Compared with the conve...

In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...
