Abstract: A digitally timed complementary metal oxide semiconductor (CMOS) rectifier for wireless power transfer in an implanted medical device is provided. According to one aspect, a voltage rectification circuit for a medical device having an internal coil and internal circuitry includes a voltage rectifier comprising a complementary metal oxide semiconductor (CMOS) circuit having low-side first type MOS transistors and upper cross-coupled second type MOS transistors. The voltage rectifier may be configured to output a rectified received voltage, each low-side first type MOS transistor being configured with an first type MOS body diode, the low-side first type MOS transistors being enabled by a timing signal to provide conduction through the low-side first type MOS transistors while bypassing conduction through the first type MOS body diode during a time window having a duration determined by voltage level crossings of the received voltage.

Abstract: A device is configured to transmit tissue conductance communication (TCC) signals by generating multiple TCC signals by a TCC transmitter of the IMD. The generated TCC signals are coupled to a transmitting electrode vector via a coupling capacitor to transmit the plurality of TCC signals to a receiving medical device via a conductive tissue pathway. A voltage holding circuit holds the coupling capacitor at a DC voltage for a time interval between two consecutively transmitted TCC signals.

Abstract: A device, such as an IMD, having a tissue conductance communication (TCC) transmitter controls a drive signal circuit and a polarity switching circuit by a controller of the TCC transmitter to generate an alternating current (AC) ramp on signal having a peak amplitude that is stepped up from a starting peak-to-peak amplitude to an ending peak-to-peak amplitude according to a step increment and step up interval. The TCC transmitter is further controlled to transmit the AC ramp on signal from the drive signal circuit and the polarity switching circuit via a coupling capacitor coupled to a transmitting electrode vector coupleable to the IMD. After the AC ramp on signal, the TCC transmitter transmits at least one TCC signal to a receiving device.
