A.1 Overview

This appendix shows the test setup used for hardware evaluation of the bootstrapped circuits and presents the test results in greater detail. Some of the circuit components, component numbers, gain setups, and operating conditions may be somewhat different than used in the discussion portion of the applications report. This was done as a matter of convenience. It does not alter the fundamental circuit topologies or the manner in which they function.
