LDO with low power consumption
Our IP can support various Power mode(Idle Mode (10mA load), Normal Mode (120mA load), Power-down Mode (No load)). And also Low Current Consupmtion(Idle Mode: Under 500nA, Normal Mode: Under 50uA including Low-Power BGR, POR).
It can adjust Output voltage within ±20mV using 6bits Resolution Trimming.
Power Management Unit for Smart Card Communication
This IP consists one DC-DC Boost converter and two LDOs. each components are compliance with ISO7816-3 power class standards.
3.3V to 1.8V, 120mA LDO(with POR)
This low drop-out voltage regulators (LDO) IP, occupying an area of 500 X 200 um2, was implemented with TSMC 0.18um 2P6M CMOS process.
The LDO IP, designed with 3.3V transistors and MIM capacitors, operates with 2.7V to 3.3V power supply
In the normal operation mode, the LDO IP supports 1.8V voltage output and covers..
A Rectifier for RF Energy Harvesting System
This RF rectifier uses the internal threshold voltage cancellation technique and quality factor multiplication technique. These techniques improve the power conversion efficiency of the rectifier as well as enable longer power transfer. Even though the floating MOS technique is used, the speed-up technique helps the fa..
High Efficiency Rectifier Circuit for WPT
The rectifier is developed from the basic cross-coupled bridge structure already developed. But the basic structure though, was more efficient compared to other MOSFET structures providing higher voltage efficiency and with minimum turn-on voltage, suffered from leakage loss due to reverse conduction at times when the ..
