| Summary: | 碩士 === 中原大學 === 電子工程研究所 === 86 === Recently, the current-mode circuits havebeen popular, because of their high bandwidths,large dynamic ranges and simple circuit configurations. The design of analog circuitsusing current-mode active components suchas current conveyors, current feedback amplifiers and operational transconductanceamplifiers is discussed in this thesis. The thesis is consisted of two topics and described as follows : Voltage-mode and current-mode filters : The designs of three-input and single-output voltage-mode universal biquadraticfilter employing second-generation current conveyors and of single-input and two-outputcurrent-mode multifunctional filter employingone current feedback amplifier are proposed. The advantages of these filters are (1) using fewer elements ; (2) low active and passivesensitivities ; (3) no requirements for componentmatching conditions (except the first circuit show in Fig. 3-3) ; and (4) the realizations of different filters from the same configuration. Impedance simulators : It employs operational transconductanceamplifiers. Two circuits which are composed of positive and negative impedance simulators are designed. Therefore, the given value of impedanceis available for the adjustable transconductance gains of operational transconductance amplifiers. The circuits depicted as above could be verifiedby experiments or simulations.
