The present invention discloses a circuit sharing time delay integrator structure. The major composing elements of this circuit sharing time delay integrator structure are: a sharing circuit, a first control block, a plurality of second control blocks and a timing set generated by a timing generator circuit. The sharing circuit can be an OP-AMP, an active load, or any of a variety of combinations used in signal accumulation applications. With the implementation of the present invention to applications of signal accumulations, the necessity of an adder circuitry is eliminated, the overall circuitry and hence the total amount of transistors required when producing the integrated circuit is massively reduced, and thus a great cost reduction and better timing and power efficiency can all be thereof achieved.
