<p>A signal processing circuit which provides an accurate continuously tunable impedance. A tunable continuous time transconductor G(s) which may for example comprise an opto-electronic inductor, has a discrete time current processor -H(z) connected between its input and its output so as to provide current feedback. The discrete time current processor may be based on a switched current memory which can be adapted to provide scaler, differentiator or integrator configurations.</p> |
