Universal Tunable Current-Mode Biquad Employing Distributed Feedback Structure with MO-CCCIIOne possible application of the multiple-output electronically-tunable active building block as a universal filter with distributed feedback structure is presented. The suggested structure is less conventional than the well-known state-variable Kerwin-Huelsman-Newcomb but allows the same filter configurations with the similar properties. The major current-mode design approach disadvantage,ie, the necessity of multiple current outputs, is demonstrated. To date even a rather big line of the commercially available devices do not solve this problem. Some features of the active block used for modelling and transistor-level simulation are briefly discussed. The obvious chance for electronic tuning of the proposed filter is verified.

In this paper, a new first-order current-mode (CM) universal filter employing two dual output second-generation current conveyors (DO-CCIIs), one resistor and a grounded capacitor is proposed. The proposed filter has low input and high output impedances; thus, it can be easily connected with other CM circuits. It can simultaneously realize first-order low-pass (LP) and all-pass (AP) responses and can provide high-pass (HP) response with interconnection of LP and AP responses. It can be tuned electronically by replacing with dual output second-generation current controlled conveyors (DO-CCCIIs) instead of DO-CCIIs and removing the resistor. It has only a resistor but no capacitor connected in series to X terminal of DO-CCII; accordingly, it can be operated at high frequencies. Also, it does not need any critical passive component matching conditions and cancellation constraints. A number of simulation results based on SPICE program are included to exhibit performance, workability and effectiveness of the proposed filter configuration.

In this paper, a new realization of a current-mode first-order all-pass filter (APF) using a single active building block (ABB) and one grounded capacitor is presented. As the ABB, the current backward transconductance amplifier (CBTA) is used, which is one of the most recently reported active elements in the literature. The theoretical results are in detail verified by numerous SPICE simulations using a new low-voltage implementation of CBTA. In the design, the PTM 90[Formula: see text]nm level-7 CMOS process BSIM3v3 parameters with [Formula: see text]0.45[Formula: see text]V supply voltages were used. The proposed resistorless CBTA-C APF provides easy electronic tuning of the pole frequency in the frequency range from 763[Formula: see text]kHz to 17.6[Formula: see text]MHz, which is more than one decade. Maximum power dissipation of the circuit is 828[Formula: see text][Formula: see text]W at bias current 233[Formula: see text][Formula: see text]A. Nonideal, parasitic effects, sensitivity analyses, temperature and noise variation, current swing capability, and Monte Carlo analysis results are also provided. Compared to prior state-of-the-art works, the proposed CBTA-C APF has achieved the highest figure of Merit value, which proves its superior performance.

This paper deals with the realization of current-mode first-order universal filter based on multiple output second generation current conveyor (MO-CCII). Two MO-CCIIs, one resistor and one capacitor are used in the circuit realization. The proposed work includes additional features such as ease of cascadability, easily implementable in modern integrated circuit technology and no requirement of passive components matching condition. The additional beauty of the proposed filter structure is that all three responses can also be realized by interchanging the positions of passive components as well. Moreover, a possible transformation of the proposed current-mode type universal filter into a voltage-mode type universal filter using network transpose method is also explored. The possibility of mode transformation further expands the scope of proposed idea. The theoretical aspects are verified using cadence VIRTUOSO simulation results.
