Abstract
An improved architecture for an implantable medical device using a primary battery is disclosed which reduces the need for boosting the voltage of the primary battery, and hence reduces the power draw in the implant. The architecture includes a boost converter for boosting the voltage of the primary battery and for supplying that boosted voltage to certain of the circuit blocks, which is particularly useful if the battery voltage is necessarily lower than the minimal input power supply voltage necessary for the circuit blocks to operate. However, circuitry capable of operation even at low battery voltages—including the telemetry tank circuitry and the compliance voltage generator—receives the battery voltage directly without boosting, thus saving power.
