Resumen

An integrated switch to control electrical stimuli in implantable medical devices is presented in this work. First a self-biased protection mechanism to avoid VGS reaching maximum rated value is presented. Then, using a HV-CMOS technology this technique is incorporated in a fully integrated switch, to control 0 to 16V, and 0 to 30 mA, pulses for implantable stimulators. Because of the low supply voltage VCC between 2 to 5V, and safety considerations in implantable devices, special level shifters, drivers, and a voltage multiplier, that drive a large 40000μm/3μm dual PMOS switch, were necessary for the circuit.
