A fuzzy membership function circuit in SC technique
Gianluca Giustolisi, G. Palmisano, Gaetano Palumbo · 2002
A new Switched Capacitor Membership Function circuit, which is based on an offset insensitive SC amplifier and presents triangular-shape transcharacteristics, is proposed. Thanks to the SC approach a good precision, which is independent of process tolerances, is achieved. The circuit was realised in a 1.2-/spl mu/m standard CMOS technology and both simulations and experimental data were carried out. Good agreement is shown between expected and measured values.
