In this work an adaptive impedance matching scheme for 2.4GHz wireless communication, based on fuzzy control, is proposed. For that purpose, a two-port passive matching network controlled by a zero-order Takagi-Sugeno-Kang fuzzy controller is used, allowing the system to iterate until the matching point is reached. Several experiments using the fuzzy(More)
In this work a programmable system for the processing with fuzzy logic is presented. The fuzzy algorithm is fully analogical and can be programmed for different applications using digital – analog converters (DAC). The circuit is biased with 3V and it is designed for a 1.5 μm CMOS technology process. The results of the simulation show the correct operation(More)
This paper presents the design of a current-feedback operational amplifier (CFOA) which is suitable for implementation with standard CMOS integrated-circuit technology of 0.35 mum. The characteristics of the CFOA are derived by using biases of plusmn2.5 V and Ibias=20 muA. The usefulness of the CFOA is demonstrated by designing mixed-mode biquads which(More)
