Abstract
A family of continuous-time and switched-current (SI) four-quadrant current-multipliers are proposed, based on a current-gain cell linearly controlled by a current, as well as an SI version of that cell. The use of a subtractor is also proposed, which eliminates current offsets. Based on this property an offset-free four-quadrant multiplier-integrator cell is also presented. The new circuits are meant to implement adaptive filters
