Power consumption reduction in medical devices by employing different supply voltages

Abstract

Power consumption in medical devices is reduced through the application of different supply voltages to analog and digital circuits, respectively. The medical device generally includes analog circuits (e.g., an atrial sense amplifier, a ventricular sense amplifier, a T-wave amplifier, bandpass filters, detection circuits, sensor amplification circuits, physiological signal amplification circuits, output circuits, a battery monitor circuit, and a power on reset circuit) and digital circuits (e.g., a processor, a controller, and a memory) with the supply voltage applied to the analog circuits being greater than that applied to the digital circuits. A source applies a first fixed supply voltage to the digital circuits of the medical device and a voltage generation circuit (e.g., a charge pump circuit) having the first fixed supply voltage applied thereto is used for generating a second fixed supply voltage to be applied to analog circuits of the medical device.
