TL;DR: In this paper, a general closed-form subharmonic stability condition is derived for buck converter with ripple-based constant on-time control and a feedback filter, and the turn-on delay is included in the analysis.
Abstract: A general closed-form subharmonic stability condition is derived for the buck converter with ripple-based constant on-time control and a feedback filter. The turn-on delay is included in the analysis. Three types of filters are considered: low-pass filter (LPF), phase-boost filter (PBF), and inductor current feedback (ICF) which changes the feedback loop frequency response like a filter. With the LPF, the stability region is reduced. With the PBF or ICF, the stability region is enlarged. Stability conditions are determined both for the case of a single output capacitor and for the case of two parallel-connected output capacitors having widely different time constants. The past research results related to the feedback filters become special cases. All theoretical predictions are verified by experiments.

Abstract: Some harsh environments, such as those encountered by missiles, rockets and various types of industrial machinery, contain high frequency mechanical vibrations. Unfortunately, some very useful components are sensitive to these high frequency vibrations. Examples include MEMS gyroscopes, oscillators and some micro-optics. Exposure to high frequency mechanical vibrations present in the operating environment can result in problems ranging from an increased noise floor to component failure. Passive micromachined silicon lowpass filter structures (spring-mass-damper) have been demonstrated in recent years. Since they usually possess a low vertical profile, they can be utilized as the packaging substrate for the sensitive component requiring vibration isolation. The performance of these filter structures is typically limited by low damping and a lack of tunability after fabrication. However, filter performance can be enhanced by integrating fluidic damping techniques with the passive filter or by integrating a ...

TL;DR: In this paper, the authors proposed a method to eliminate the need of adjustment of a semiconductor integrated circuit before and after the circuit is mounted and, at the same time, to perform highly accurate correction on the circuit and minimize the area occupied by the circuit even when its scale is increased.
Abstract: PURPOSE:To eliminate the need of adjustment of a semiconductor integrated circuit before and after the circuit is mounted and, at the same time, to perform highly accurate correction on the circuit and minimize the area occupied by the circuit even when its scale is increased CONSTITUTION:This semiconductor integrated circuit is provided with a filter circuit block 1 incorporating an amplifier 5 which requires adjustment, PROM 4 which stores adjustment data, D/A converter 3 which converts the data of the PROM 4 into analog data, and V/I converter 2 which adjust the mutual conductance of the amplifier 5 in the block 1 by performing voltage-current conversion on the analog output of the converter 3 Therefore, a highly accurate characteristic can be obtained when appropriate data are written in the PROM 4 at the time of inspecting a wafer or during the course of a screening process after assembling the wafer

TL;DR: In this paper, the authors present general practical issues related to active power filters, specifically for the medium voltage range, for the purpose of Harmonic mitigation in power system, which can be achieved by two approaches, one considering fully controlled converter, which increases complexity and cost and the other using filters.
Abstract: Research into active filters for the medium voltage range is ongoing. This paper presents general practical issues related to active power filters, specifically for the medium voltage range. Harmonic mitigation in power system occupied a great deal of research which can be achieved by two approaches, one considering fully controlled converter, which increases complexity and cost and the other using filters. Passive filters are cheap, simple and easy for maintenance.
