In this paper, a block based systematic approach for synchronous design of linear filters and oscillators through full design space exploration is presented, which exploits inherent hierarchical property of tree. To bridge the gap between system specification and hardware structure of analog system, transfer function of linear filter and characteristic equation of oscillator have been modeled using a rooted tree, formed based on the characteristics of four basic building blocks. A hardware conversion algorithm has been used to map the paths of the tree into operational transconductance amplifier (OTA) based circuits, implementing both programmable linear filter and oscillator. Twenty seven distinct architectures for filters and oscillators are generated. The proposed approach is also compatible with Field Programmable Analog Array (FPAA), as demonstrated by mapping the generated circuits into a hexagonal FPAA.

本文提出了一种基于块的系统方法，通过充分利用设计空间来进行线性滤波器和振荡器的同步设计，该方法利用了树的固有分层特性。为了弥合系统规格和模拟系统的硬件结构之间的差距，使用了基于四个基本构件的特征的根树对线性滤波器的传递函数和振荡器的特性方程进行了建模。硬件转换算法已用于将树的路径映射到基于运算跨导放大器（OTA）的电路中，从而实现可编程线性滤波器和振荡器。生成了用于滤波器和振荡器的27种不同的体系结构。拟议的方法还与现场可编程模拟阵列（FPAA）兼容，
