Impact of NBTI-Induced Pulse-Width Modulation on SET Pulse-Width Measurement

IEEE Transactions on Nuclear Science, 2013
This paper gives an explanation that SET pulse-width modulation in bulk CMOS devices happens due to negative bias temperature instability (NBTI). To investigate this, we propose and implement a stress adjustable pulse-width measurement circuit. Measurement results of test chips fabricated in a 65nm bulk CMOS process clearly show that pulse-width ...

Pulse-width modulation in sigma-delta modulators

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
Time-encoding machines map analog or multi-bit digital signals to a binary stream. The information contained in the input signal is preserved by the high resolution achieved in the time domain. Pulse-Width Modulators (PWMs) rely on a similar operation principle.

Sliding Mode Pulse Width Modulation

2007 American Control Conference, 2007
This paper presents sliding mode pulse width modulation (SMPWM) control methodologies for a current- controlled inverter. Discussion begins with circuit analysis, proper references, and design of sliding surfaces. Based on this formulation, two novel approaches adopt sliding mode concept are proposed to make the system tracking selected references ...

Pulse width modulated optical OFDM

2015 IEEE International Conference on Communication Workshop (ICCW), 2015
In this paper, the PWM encoding of an optical OFDM transmission is studied and simulated. Traditional optical OFDM schemes make use of linear drivers, but the inherent nonlinear behavior of the optical emitters produce a harmful effect on the demodulated signal.
