Abstract: A TOTALLY-INTEGRATED battery controller for implantable telemetry systems will be described. Featuring an RF detector with a 1mV sensitivity and a standby power of 300nW, the system utilizes an on-board 12L ring-oscillator divider t o determine the on-time of the implant package, to establish acceptable input activation signals, and to enable serial programming of on-time.Classically, battery-powered systems have been actuatcd either by such nonlatching excitation as continuous RF' or by latchin sources such …
