A new low-power low-voltage active resistor structure with improved performances will be presented. The problem of circuit linearity is solved by implementing an original technique, using a proper current biasing of the differential core, while the existing solutions allow only a partial improvement of the circuit performances. The structures are implemented in m 35 . 0  CMOS technology and ar...

This paper proposes performance based macro modeling of analog circuit using Multi Output Modeling (MOM) with the help of Support Vector Machine (SVM). SVM models the analog circuits and provides a relation between multi-input and multi-output parameters. In this work, Voltage Controlled Oscillator (VCO) is modeled as a test circuit which is designed in Cadence Virtuoso GPDK 45nm technology. Fr...

This study presents a new current-mode singleinput and multi-output (SIMO) type universal biquad circuit using second generation multi-output current conveyors (MOCCII) as the active components. The proposed circuit employs three MOCCIIs, two grounded capacitors and four grounded resistors, therefore offers electroning tuning possibilities. It can simultaneously realize second order low-pass, b...

This paper presents a hybrid CMOS-CNFET voltage controlled oscillator (VCO) with low power dissipation and linear response over a wide control voltage range. The hybrid circuit is based on PTM 32nm low power CMOS devices and 32nm CNFET devices with different threshold voltages. The VCO frequency and power dissipation are investigated for CNFET parameters such as number of nano-tubes, gate oxide...

Printed Circuit Board (PCB) of 50mm (L) x 10mm (W) x 0.8mm (H). The Printed Circuit Assembly is composed of a set of case A ATC capacitors (American Technical Ceramic, New York) allowing a 63.7 MHz tuning and a 50 Ω matching. An active decoupling circuit was also included using a PIN diode (Temex DH 80106 PIN diode) driven by the MR system during RF pulse transmission. As for the optical modali...
