Enhanced Pathological Element-Based Symbolic Nodal Analysis
An improved symbolic analysis procedure to enhance the analytic efficiency of the reported symbolic nodal analysis is presented. Two techniques are adopted in the proposed method to reduce the order of the system of equations when performing symbolic analysis. The first one uses voltage signal sources directly to perform symbolic analysis without replacing them with their nullor equivalences. The second one uses the nullor, grounded mirror, and floating mirror elements to model the active devices that involve differential or multiple single-ended signals. Practical examples are given which demonstrate the feasibility of the proposed methods.

UNIVERSAL VOLTAGE-MODE BIQUADRATIC FILTER SYNTHESIS USING NODAL ADMITTANCE MATRIX EXPANSION
Bài báo này trình bày một thuật toán tổng hợp có hệ thống nhằm tạo ra các mạch lọc đa năng bậc hai chế độ điện áp trên cơ sở phương pháp mở rộng ma trận. Tám mạch tương đương được tạo ra có thể thực hiện tất cả năm chức năng lọc cơ bản là lowpass, bandpass, highpass, notch và allpass sử dụng chỉ hai linh kiện tích cực. Các mạch được tạo ra có những chức năng lợi thế sau: 5 lối vào và 2 lối ra, cấu hình mạch đơn giản, tần số và hệ số Q có thể điều khiển trực giao nhau, độ nhạy với nhiễu của linh kiện tích cực và thụ động thấp. Sự hoạt động của các mạch tạo ra được kiểm chứng bằng hệ phần mềm mô phỏng HSPICE, chứng minh tính hữu dụng của phương pháp đề xuất.

Synthesis of Cascadable DDCC-Based Universal Filter Using NAM
A novel systematic approach for synthesizing DDCC-based voltage-mode biquadratic universal filters is proposed. The DDCCs are described by infinity-variables’ models of nullor-mirror elements which can be used in the nodal admittance matrix expansion process. Applying the proposed method, the obtained 12 equivalent filters offer the following features: multi-input and two outputs, realization of all five standard filter functions, namely lowpass, bandpass, highpass, notch and allpass, high-input impedance, employing only grounded capacitors and resistors, orthogonal controllability between pole frequency and quality factor, and cascadable, low active and passive sensitivities. The workability of some synthesized filters is verified by HSPICE simulations to demonstrate the feasibility of the proposed method.

Derivation of Oscillators from Biquadratic Band Pass Filters Using Circuit Transformations
Network transformations are the techniques to obtain new functional schemes from available circuits. They are systematic methodologies, since each transformation technique can be applied to many circuits to obtain the desired functions or characteristics. A convenient network transformation method, exploiting different circuit transformations, for deriving linear sinusoidal oscillators from biquadratic band pass filters is proposed. This method with generality can be applied to any band pass filter. The oscillation frequency of the new obtained oscillator is identical to the center frequency of the original band pass filter, and the useful properties of the selected band pass filter can be retained. Two examples are illustrated to confirm the feasibility of the proposed approach. The workability of the obtained oscillators is verified with PSPICE simulations.
