This paper introduces a new current-mode approach based configurable analog block (CAB) operating in voltage-mode with high input resistance, employing only three impedances in grounded form and providing a wide range functionality. The fourteen functions realized by the CAB include amplifiers, integrators, differentiators, and filters. The nonideal and parasitic analysis of the proposed configurable block is carried out, along with detailed simulation studies using 0.25μm CMOS parameters and a supply of ±0.75V for justifying the advance to the field. The active element used for designing the CAB exhibits 1.9 and 0.8GHz as voltage and current transfer bandwidths, respectively, while also providing low output resistance of 105Ω in voltage conveying action. Thus, the proposed CAB benefits from high frequency performance and lesser sensitivity to errors due to parasitic at that terminal. Most of the functions utilize beneficial form of grounded components. Presentation of conclusive results for integrator, all-pass filter and band-pass filter is included in form of frequency and transient responses. In-depth intermodulation distortion results for band-pass filter are further given. General conclusive annotations on analog circuit design are made at the end of this study.

本文介绍了一种新的基于电流模式方法的可配置模拟模块 (CAB)，该方法在具有高输入电阻的电压模式下工作，仅采用三个接地形式的阻抗并提供广泛的功能。CAB实现的十四种功能包括放大器、积分器、微分器和滤波器。对提议的可配置模块进行了非理想和寄生分析，并使用 0.25 进行了详细的仿真研究μm CMOS参数和供应±0.75V 用于证明向该领域推进的合理性。用于设计 CAB 的有源元件表现出 1.9 和 0.8GHz 分别作为电压和电流传输带宽，同时还提供 105 的低输出电阻Ω在电压输送动作中。因此，所提出的 CAB 受益于高频性能和对由于该终端寄生而导致的错误更不敏感。大多数功能利用接地组件的有益形式。积分器、全通滤波器和带通滤波器的结论性结果以频率和瞬态响应的形式呈现。进一步给出了带通滤波器的深入互调失真结果。本研究结束时对模拟电路设计进行了一般结论性注释。
