Application Information
arrange the CMOS digital circuitry around it (since this also
generates noise), and then place sensitive preamplifiers and

IF stages on the diagonally opposing corner. Often, the
sensitive circuitry is shielded with a metal pan and power to
it is post-regulated to reduce conducted noise, using low-
dropout linear regulators.
