| | PDF (273 KB)

Cascaded integrator comb (CIC) filters are in wide use in oversampled analog-to-digital converters. In this study, the authors advances three new cascaded decimator structures with integer coefficients designed using a polynomial factorisation approach. Each one of the designed decimators shows better stopband attenuation for a given order and decimation factor than the CIC or recently proposed ge... View full abstract»

• ### On the use of Karatsuba formula to detect errors in GF((2(sup)n(/sup))(sup)2(/sup)) multipliers

Galois fields are widely used in cryptographic applications. The detection of an error caused by a fault in a cryptographic circuit is important to avoid undesirable behaviours of the system that could be used to reveal secret information. One of the methods used to avoid these behaviours is the concurrent error detection. Multiplication in finite field is one of the most important operations and ... View full abstract»

• ### Configuration for realising a current-mode universal filter and dual-mode quadrature single resistor controlled oscillator

Publication Year: 2012, Page(s):159 - 167

| | PDF (740 KB)

A new universal single input multiple output (SIMO)-type universal filter configuration using three dual output current conveyors (DOCCII) and five grounded passive elements is proposed which can realise all the five basic filtering functions namely low pass, high pass, band pass, band stop and all pass in current mode from the same configuration. With appropriate modification of one connection, t... View full abstract»

• ### High-Q metamaterial interdigital transmission line based on complementary spiral resonators for low phase noise voltage-controlled oscillator

Publication Year: 2012, Page(s):168 - 175
| | PDF (637 KB)

In this study, the high-quality factor (Q) metamaterial interdigital transmission line (TL) based on the complementary spiral resonators (CSRs) is presented for reducing the phase noise of the voltage-controlled oscillator (VCO). The high-Q metamaterial TL is realised by adopting the array of the CSRs etched on the ground plane and the interdigital centre line on the signal plane. Th... View full abstract»

• ### Multi-resolution based sensitivity analysis of complex non-linear circuits

Publication Year: 2012, Page(s):176 - 186
Cited by:  Papers (7)
| | PDF (613 KB)

This study addresses the sensitivity analysis of non-linear circuits in their transient and periodic behaviour. The circuits here considered are built of connections of N-ports with frequency-dependent parameters whose input and output quantities are expanded in the wavelet domain. The use of wavelet instead of the Fourier analysis allows a significant increase in the sparsity of the matric... View full abstract»

• ### High-quality factor asymmetric-slope band-pass filters: A fractional-order capacitor approach

Publication Year: 2012, Page(s):187 - 197
Cited by:  Papers (11)
| | PDF (1163 KB)

This study presents new techniques for implementing continuous-time second-order band-pass filters with high-quality factors and asymmetric slopes. The techniques are centred around the realisation of two non-conventional transfer functions which include the non-integer-order Laplacian operator sα; 0<;α<;1. Four main possible circuit realisations; one based on... View full abstract»

• ### Subthreshold CMOS voltage reference circuit with body bias compensation for process variation

Publication Year: 2012, Page(s):198 - 203
Cited by:  Papers (4)
| | PDF (404 KB)

This study presents a subthreshold complementary metal oxide semiconductor (CMOS) voltage reference circuit that adopts dynamical body bias to compensate the process-related reference voltage fluctuation. The proposed circuit generates a mean reference voltage of 0.781 V at 1.2 V supply and 27°C, reduces the standard deviation (σ) of the reference voltage from 11 mV to only 3 mV, and...

• ### Non-linear coupling voltage of split-gate flash memory cells with additional top coupling gate

Publication Year: 2012, Page(s):204 - 210
Cited by:  Papers (1)
| | PDF (325 KB)

The study presents the dependence of floating gate (FG) coupling potential, VFG on the source line (SL) programming voltage, VSL of the split-gate flash memory cells with an additional top coupling gate above FG, called the SG-TCG cells. The mathematical analysis shows non-linear VFG against VSL behaviour of SG-TCG cells dep... View full abstract»
