Error control in simplification before generation algorithms for symbolic analysis of large analogue circuits [PDF]
, 1999 Circuit reduction is a fundamental first step in addressing the symbolic analysis of large analogue circuits. A new algorithm for simplification before generation is presented which is very efficient in terms of speed and the amount of circuit reduction,

Analogue adaptive neural network circuit [PDF]
IEE Proceedings G Circuits, Devices and Systems, 1991 Current integrated circuits realising neural networks take up too much area for implementing synapses. The paper presents a one-transistor (IT) synapse circuit that uses a single MOS transistor, which is more efficient for VLSI implementation of adaptive neural networks, compared to other synapse circuits.

CMOS 2.4μm chaotic oscillator: Experimental verification of chaotic encryption of audio [PDF]
, 1996 The Letter reports the first experimental verification of chaotic encryption of audio using custom monolithic chaotic oscillators. We use Gm-C techniques to realise a chaotic modulator/ demodulator IC that implements a 3rd-order nonlinear differential ...

Unconstrained evolution of close-to-ideal "LCR" low-pass filter [PDF]
The unconstrained evolution has already been applied in the past towards design of digital circuits, and extraordinary results have been obtained, including generation of more compact circuits with smaller number of electronic components.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Electronics Letters, 2023 A three‐stage rail‐to‐rail bulk‐driven class AB OTA that operates with ±0.15 V supplies and a power dissipation of 90 nW is introduced. The first two stages use resistive local common mode feedback. The OTA uses simple phase lead compensation.
