Abstract
A high-resolution neurostimulator is the essential
component of many bidirectional neural interfaces. In practice,
the effective resolution of fully integrated neurostimulator designs
is often hindered by the transistor mismatch, especially in
submicrometer CMOS processes. In this article, we present a
new circuit technique called redundant crossfire (RXF) to address
this challenge. It is derived from our redundant sensing (RS)
framework, which aims at engineering information redundancy
into the
