engineering practice to make signal trace lengths as
short as possible. Also recommended are a ground
plane and surface mount resistors and capacitors.
Input Noise
Radiated noise is common in low power circuits that
require high impedance circuits. To minimize this
effect, all traces between any of the inputs and
passive component networks should be made as
short as possible.
