ABSTRACT: Tow different
computer calculation methods for distortion of the wide-band diode bridge track
and hold amplifier (THA) are presented based on a high frequency Schottky diode
model. One of the computer programs calculates
the distortion of weekly nonlinear THA based on the KCL and the
nonlinear-current method. The other calculates the weekly nonlinear distortion
by using a Volterra series method and a nodal formulation. Comparative
calculation results for the diode bridge THA have shown good agreement with
these two computer program calculation methods, whereas the overall
computational efficiency of the nonlinear-current method is better than that of
the nodal formulation method in a special evaluation.
