Background:

Conventional micro-stimulators often rely on complex Field-Programmable Gate Arrays (FPGAs) or Microcontroller Units (MCUs) for pulse generation.
This complexity increases circuit size, cost, and programming requirements for implantable systems.

Purpose of the Study:

To present a novel, implantable micro-stimulator design that simplifies circuit complexity and reduces cost.
To demonstrate the efficacy of pulse width modulation (PWM) as a control mechanism, eliminating the need for traditional computerized controllers.

Main Methods:

The proposed micro-stimulator chip utilizes pulse width modulation (PWM) for controlling stimulation parameters.
It incorporates a 5-bit programmable current selectivity for precise amplitude control.
