Abstract
A new switched-current cell is presented which simultaneously offers high speed, low distortion, low gain error, and a virtual ground input. In a simulation example 0.01% distortion was achieved at 50 MHz sampling rate which makes the cell very well suited for high accuracy high speed filtering applications. It is outlined how the cell can be used in FIR filtering and to form integrators with high DC gain and low distortion
