Abstract

This paper presents an energy-efficient 15.7-V-compliant current-mode stimulator with a proposed boost-based dynamic voltage supply that minimizes the stimulator's voltage dropout. The boost uses a proposed 8-bit quantizer that measures the voltage ratio of its output to the input to digitally achieve the discontinuous conduction mode (DCM). A low-power high-voltage gate driver with a short switching transient time is proposed to improve energy efficiency. The converter achieves 90.2% peak efficiency, and up to 86% end-to-end energy efficiency is realized when a 6-mA biphasic stimulation is carried out. The stimulation IC is fabricated in 0.18 μ m Bipolar-CMOS-DMOS (BCD) technology and occupies an area of 2.16 mm2. This stimulator consumes a low static power of 1.78 μ W, promising battery-powered implants with a long lifetime and a small form factor.
