Abstract :
The concepts behind externally linear, internally nonlinear integrators are reviewed, and the contest in which such integrators can find use in signal processing is discussed. Several examples of specific cases are offered, including log-domain, exponential state space, square root domain, piecewise-linear, and nonlinear capacitance circuits. Several issues requiring caution are discussed
