CRITICALLY-DAMPED COMPENSATION FOR BROADBAND AMPLIFIERS

Abstract

Lossless critically-damped 2-ter inal and 3-terminal ladders are considered as a means of compensating for parasitic shunt capacitance in broadband amplifiers. Equations are presented that simplify the design of these ladders. The capacitance and inductance values are tabulated for ladders that contain up to 7 reactive elements. The analysis is extended to the limiting case of an infinite number of elements. The element values and transient responses of these optimum ladders are derived. Using a figure of merit that is based on the slope of the step response at its half-amplitude point, the infinite 2-terminal ladder is 59% better than an uncompensated circuit while the 3terminal ladder is 117% better.
