On the suitability and development of layout templates for analog layout reuse and layout-aware synthesis [PDF]
, 2005 Accelerating the synthesis of increasingly complex analog integrated circuits is key to bridge the widening gap between what we can integrate and what we can design while meeting ever-tightening time-to-market constraints.

Improving the Signal to Noise Ratio of QTF Preamplifiers Dedicated for QEPAS Applications
Applied Sciences, 2020 The signal-to-noise ratio (SNR) is a major factor that limits the detection sensitivity of quartz-enhanced photoacoustic spectroscopy (QEPAS) sensors. The higher the electrical signal level compared to the noise amplitude is the lower the concentration ...

Frequency response and gap tuning for nonlinear electrical oscillator networks. [PDF]
PLoS ONE, 2013 We study nonlinear electrical oscillator networks, the smallest example of which consists of a voltage-dependent capacitor, an inductor, and a resistor driven by a pure tone source. By allowing the network topology to be that of any connected graph, such

Gain- and Loss-Induced Topological Insulating Phase in a Non-Hermitian Electrical Circuit
Physical Review Applied, 2020 There have been considerable efforts devoted to the study of topological phases in certain non-Hermitian systems that possess real eigenfrequencies in the presence of gain and loss. However, it is challenging to experimentally realize such non-Hermitian topological insulators in either quantum or photonic systems, due to the difficulties in introducing

Ultra Low-Power Analog Median Filters [PDF]
, 2013 The design and implementation of three analog median filter topologies, whose transistors operate in the deep weak-inversion region, is described. The first topology is a differential pairs array, in which drain currents are driven into two nodes in a ...
