Abstract :
This paper reports a fully-integrated multi-output CMOS power regulator designed for telemetry-powered implantable microsystems. It is comprised of a CMOS full-wave bridge rectifier, a wide-range multi-output voltage reference and DC level shifter circuits, and three linear voltage regulators. The power regulator fabricated in a 1.5mum standard CMOS process, provides 5V, 3V, and 1.5V regulated outputs, exhibits load regulation factor of as low as 5% when delivering up to 17.3mA load current, and demonstrates line regulation factor of as low as 0.3%/V over 1.8-V input amplitude variation
