This study presents an electronically tunable configuration for the design of a voltage-mode (VM) biquad with four input terminals and three output terminals. The proposed circuit employs operational transconductance amplifiers (OTAs) two grounded capacitors. Depending on selections voltage signals, all standard filtering functions can be realized. simultaneously provides VM inverting band-pass...

This paper presents a 52-to-57 GHz CMOS quadrature voltage-controlled oscillator (QVCO) with novel I/Q phase tuning technique based on body bias control method. The QVCO employs an in-phase injection-coupling (IPIC) network comprising four diode-connected FETs for the generation. error is calibrated by controlling voltage offset of QVCO’s core FETs. effectively covers wide range between −13.4° ...

In this paper, we investigate the relation between the curvature of the physical space and the deformation function of the deformed oscillator algebra using non-linear coherent states approach. For this purpose, we study two-dimensional harmonic oscillators on the flat surface and on a sphere. With the use of their algebras, we show that the two-dimensional oscillator algebra on a surface can b...

In this paper, we investigate the relation between the curvature of the physical space and the deformation function of the deformed oscillator algebra using non-linear coherent states approach. For this purpose, we study two-dimensional harmonic oscillators on the flat surface and on a sphere by applying the Higgs modell. With the use of their algebras, we show that the two-dimensional oscillat...

This paper presents the ring oscillator based temperature sensor. The method is highly area efficient, simple and easy for IC implementation as compared to traditional temperature sensors. The proposed temperature sensor was fabricated using 0.35 μm technology, which occupies extremely small silicon area. It exploits the frequency of the ring oscillator that is proportional to temperature, whic...

Two chaos generator circuits using dual-output second-generation current conveyors [DO-CCIIs] as active devices with grounded passive components are realized. The starting circuit is a voltage-mode four-phase sinusoidal quadrature oscillator [VMFPSQO] circuit for realizing both the chaos generators. The first chaos generator is derived by modifying the VMPFSQO by inserting an additional frequen...
