Resumen
Descripción
In this work, the design and implementation of a 25mA (max), 8 bits integrated programmable current source for implantable medical devices is presented. The proposed circuit includes a six-bits trimming mechanism to balance sink/source outputs to a precision below 1%. The current source is powered by an external supply voltage of up to 10V. The circuit was fabricated in a 0.18um HV CMOS technology, some preliminary measurements are also presented showing a close agreement with previously simulated results.
