摘要： A current and temperature compensated voltage reference circuit uses a power supply voltage as low as 1.3 Volts. A folded-cascode amplifier measures the temperature dependent voltages provided by first and second bias circuits, each including two series-coupled diodes or diode-connected bipolar junction transistors (BJTs), and provides a resulting proportional to absolute temperature (PTAT) current through a cascode-protected output transistor. A voltage reference circuit uses a PTAT current through a resistor to create a PTAT voltage in series with a diode-voltage. The resistor value is adjusted until the sum of these voltages is equal to the bandgap voltage of silicon, providing a temperature compensated voltage reference. The reference circuit is suitable for use with an implantable cardiac rhythm management system having a battery that provides a power supply voltage varying approximately between 1.3 Volts and 3.25 Volts. Cascode-protected current mirrors further improve rejection of such variations in the power supply voltage.

摘要： A bandgap voltage reference circuit implemented on an integrated circuit chip in which a proportional-to-temperature current is controlled by a current controlling resistor and converted to a voltage by a voltage controlling resistor, with either or both of the resistors being an integrated on-chip digitally trimmable resistor. The reference circuit is particularly suitable for application to circuitry used in implantable medical devices where off-chip resistors provide a channel by which noise can interfere with the operation of the circuit. The on-chip digitally trimmable resistor is implemented in accordance with the invention by a programmable switch matrix connected to a resistor network.

摘要： A differential discrete-time signal processing channel differentially processes cardiac signals in an implantable cardiac rhythm management device. Such signal processing effectively uses downsampling to uses lower bias currents, thereby saving power and prolonging the life of the implanted device, and also reduces clock feedthrough, provides a wider dynamic range and better rejection of power supply noise. The device includes a continuous-time buffer, a decimator/averager and/or other filter and/or amplifier circuits, and an analog-to-digital converter, each configured for processing differential signals. The device also includes an operational transconductance amplifier (OTA), for the discrete-time differential signal processing. The OTA provides, among other things, an output common mode adjustment circuit and an offset compensation circuit.

摘要： A power management system for an implantable device is disclosed. One application is an implantable cardioverter/defibrillator. Charging circuits for implantable cardioverter/defibrillators require relatively large currents from the power supply. The present power management system provides extended device operation and reduced charge cycle time. The present system monitors both current and voltage drawn from the power supply to prevent a loss of system voltage. Elective replacement indication is performed using charging information provided by the present power management system.

摘要： A neural stimulation system includes a safety control system that prevents delivery of neural stimulation pulses from causing potentially harmful effects. The neural stimulation pulses are delivered to one or more nerves to control the physiological functions regulated by the one or more nerves. Examples of such harmful effects include unintended effects in physiological functions associated with autonomic neural stimulation and nerve injuries caused by excessive delivery of the neural stimulation pulses.
