In this study, current-mode square-root-domain (SRD) electronically-tunable universal filter is proposed. The proposed circuit has one input and five outputs and can realize low-pass (LP), band-pass (BP) high-pass (HP) allpass (AP) and notch (N) responses without any changes in the circuit topology. In order to get variable quality factor value, the feedback is applied to the filter. Only MOS transistors...
In this paper, a new current-mode second-order square-root-domain notch filter is proposed. The design is based on the state-space synthesis method with two subcircuit; square-root and squarer/divider circuits. In the circuit, the input and the output values, and dominant variables are all currents. Only MOS transistors and grounded capacitors are required to realize the filter circuit. Three cases...
In this paper, current-mode second-order square-root-domain highpass, and allpass filters are proposed by using only a circuit. Literature survey showed that, current-mode second-order highpass and allpass filters are not proposed. The proposed circuit is derived from first-order blocks. The presented of the first-order blocks are based on the state-space synthesis method with two subcircuit; square-root...
In this paper, a new current-mode second-order differential type class-AB log-domain universal filter is proposed. The design is based on the state-space synthesis method. It has simple differential type class-AB structure and using minimum components. The proposed filter has one input and five outputs and can simultaneously realize lowpass (LP), highpass (HP), bandpass (BP), notch (N), and allpass...
In this paper, a new current-mode second-order differential type Class-AB log-domain notch filter is proposed. It is systematically designed using state-space synthesis method. The filter circuit is current-mode, Class-AB and differential type. In the circuit, the input and the output values, and dominant variables are all currents. Input and output currents are also differential signals. Only transistors...
A new log-domain first-order multifunction filter is proposed in this paper. The proposed filter is systematically derived using the state-space synthesis procedure from a corresponding block diagram. It provides lowpass, highpass, and allpass responses simultaneously for a single input signal. The filter circuit has a very simple structure, since it uses only BJTs and a grounded capacitor. It can...
