Title:
CIRCUIT DEVICE FOR PROCESSING SAMPLED ANALOG ELECTRIC SIGNALS
Document Type and Number:
Japanese Patent JPH02246412
Kind Code:
A
Abstract:
PURPOSE: To improve the current adding accuracy of a circuit device by providing a current adding node connected to the input of a current transmitting circuit to a means which couples the input sample current in the present sampling period with the input sample currents in preceding sampling periods at a prescribed rate. CONSTITUTION: An input 1 is supplied to a signal processing circuit 5 through a sample and hold circuit 3 and a current exchanger 4. The circuit 5 processes signals by coupling the current in the present sampling period with the currents in one or more preceding sampling period at a desired section and is provided with a current adding node connected to the input of a current transmitting circuit. The current transmitting circuit transmits a current between much different impedances. Therefore, currents can be added to each other with high accuracy.
