DC-DC Buck Converter Using Analog Coarse-Fine Self-Tracking Zero-Current Detection Scheme
This paper proposes a DC-DC buck converter using an analog coarse-fine self-tracking zero-current detection (AST-ZCD) scheme. The AST-ZCD detects the zero-current by measuring the voltage level across a freewheeling transistor. It adjusts the nMOS turn-off time using an amplifier, capacitors, and current sources instea..
Energy harvesting assisted self-powered electronics systems are picking up in momentum, due to the fast growing market of the Internet of Things (IoT) sensor networks. Environmental energy harvesting has attracted much attention as a possible power source for remote electronic devices and implanted/embedded electronics..
Low switching noise DC-DC Converter
This IP is a low switching noise buck dc-dc converter with a spread spectrum clock generator. Depending on the SSCG Control, this dc-dc buck converter changes the switching frequency along with the structure of Sawtooth Generator with Spread Spectrum Clock Generator. Thus it maintains a low noise shaping capability and..
Low Noise Buck DC-DC Converter
This IP is a low switching noise buck dc-dc converter with a delta-sigma modulator (DSM). Depending on the load current, this dc-dc buck converter changes the sampling frequency along with the structure of DSM between 3rd order and 2nd order loop filters. Thus it maintains a robust noise shaping capability and reduces ..
