Impact of NBTI-Induced Pulse-Width Modulation on SET Pulse-Width Measurement
IEEE Transactions on Nuclear Science, 2013This 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, 2010Time-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, 2007This 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), 2015In 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.

Pulse Width Modulation’s Impact
2021PWM technologies have multiple impacts on the power electronics converters. First, the switching losses of power electronics devices will be accumulated together with PWM and impact the converter power losses. Second, pulse voltage will cause ripple on the passive components in the output side.

Principle of Pulse Width Modulation
2021In Chap. 1, the basic concept of pulse width modulation has been introduced briefly. In this chapter, the principle of pulse width modulation will be further discussed. Based on fundamental principle, space vector PWM (SVPWM) and carrier-based PWM (CBPWM) will be presented, respectively, together with the relationship between these two approaches. With

A prefilter equalizer for pulse width modulation
Signal Processing, 2012This article demonstrates the feasibility of pulse-width-modulation (PWM) of discrete time signals in a digital audio amplifier without inducing the nonlinear distortion usually associated with straightforward PWM. This is achieved by prefiltering the signal prior to the PWM mapping in such a manner that the overall result is distortion-free.
