Dynamic signal processing with currents

当今的数字计算机和通信设备，如移动的电话，包含连续时间滤波器作为必要和重要的组件。我们将研究一种集成电路设计方法，用于创建完全可编程版本的此类滤波器。目前，这些滤波器针对每个应用重新设计，并且通常在IC外部。这增加了设计的尺寸和成本。该方法的另一成果是电流域信号处理器。这将能够模拟复杂的系统，如生物神经元和股票期权定价。我们将建立这些系统，并将它们与数字计算机连接。

Today's digital computers and communications devices, such as mobile phones, contain continuous time filters as necessary and important components. We will investigate an integrated circuit design methodology for the creation of fully programmable versions of such filters. Currently these filters are redesigned for each application and are often external to the IC. This increases the size and cost of the design. Another outcome of the methodology is a current domain signal processor. This will be capable of modelling complex systems such as biological neurons and stock option pricing. We will build these systems and interface them with digital computers.
