Adaptive translinear analog signal processing: a prospectus

We have devised a systematic method of transforming high-level time-domain descriptions of linear and nonlinear adaptive signal-processing algorithms into compact, continuous-time analog circuitry using basic units called multiple-input translinear elements (MITEs). In this paper, we describe the current state of the art and illustrate the method with an example of an analog phase-locked loop (PLL).
