A true low voltage class-AB current mirror
(2005)
Class-AB circuits, which are able to deal with currents which are orders of magnitude larger than their quiescent current, are good candidates for low-power analog design. This paper presents a new, simple, class-AB ...

Modeling dispersion of partial discharges due to propagation velocity variation in power cables
(Elsevier, 2016)
Existing models for partial discharge (PD) propagation based on a single attenuation constant are unable to explain how each frequency component travels with a different propagation velocity. This paper proposes a new model ...

Correction of errors and harmonic distortion in pulse-width modulation of digital signals
(Elsevier GmbH, 2021)
Pulse-Width (PW) modulation is widely used in those applications where an analog or digital signal has to be encoded in the time domain as a binary stream, such as switched-mode power amplifiers in transmitters of modern ...

LDO compensation with variable Miller series resistance
(The Institution of Engineering and Technology, 2014)
A new compensation method for low dropout (LDO) voltage regulators is proposed, where the series resistor of the conventional Miller compensation changes with the load current to track the variations in the first non‐dominant ...

CMOS fuzzifier using mixed-signal techniques with emphasis in power consumption
(1999)
A novel mixed-signal CMOS membership function generator (MFG) is presented. It is based on an enhanced version of a linear tunable transconductor proposed in [1] and implements trapezoidal/triangular functions with all ...
