Publisher: | Wiley | Abstract: | This paper introduces a second-order voltage-mode (VM) multiple-input single-output (MISO) universal filter and a second-order current-mode (CM) single-input multiple-output (SIMO) multifunction filter. The introduced VM MISO universal filter includes a single current feedback operational amplifier (CFOA) and a single voltage follower as active elements, while the introduced CM SIMO multifunction filter contains two CFOAs. Both introduced circuits are orthogonally controllable. In other words, the quality factors can be controlled through a single resistor without affecting the resonance frequencies. Both circuits have low sensitivities and no passive element-matching conditions. The introduced VM MISO universal filter has a low output impedance. Moreover, to extract the output currents of the proposed CM SIMO from high impedance terminals, second-generation current conveyor-based version of the circuit is introduced. Simulations are made through the PSPICE program, where 0.13-mu m IBM CMOS technology parameters are utilized. DC supply voltages are selected as +/- 0.9 V. In the experiments, AD844s are used, and DC supply voltages are chosen as +/- 7.5 V. This paper introduces a second-order voltage-mode multiple-input single-output universal filter and a second-order current-mode (CM) single-input multiple-output multifunction filter. Moreover, to extract the output currents of the proposed CM filter from high impedance terminals, second-generation current conveyor-based version of the circuit is introduced.image | URI: | https://doi.org/10.1002/cta.3920 https://hdl.handle.net/11499/56701 |
