Abstract :
A switched-current integrator configuration with greatly improved insensitivity to transistor mismatch is described. A universal integrator configuration is developed which performs an algorithm identical to the well known switched-capacitor universal integrator. This permits signal flowgraph synthesis of switched-current filters with similar properties to those of their switched-capacitor counterparts.
