A driver circuit includes two high-side switches and a single low-side switch, output inductor, and output capacitor. By having multiple high-side switches, the driver can regulate power from multiple charging devices. The high-side switches share a channel with an input capacitor for that channel and the channels are connected to the low-side switch at a common node. When the capacitor for one of the channels becomes charged quickly, the capacitor of the other channel will balance itself with the charged capacitor. To avoid damaging the high-side switches, a low-impedance bridge and driver circuit is connected between the channels.

An implantable bio-sensing platform architecture that enables the wireless selection, calibration and reading of multiple sensors, as well as checking the power levels of the solar powering source energizing various electronic and optoelectronic devices and circuits embedded in the platform. It also permits checking the operation of the potentiostats interfacing with each amperometric analyte sensor. The platform is flexible to include FET based sensors for protein sensing as well as other applications including pH sensing. In addition, other physiological sensors can be integrated in the platform.
