Title: Output device for solid-state image pickup element
Inventor: SUGIKI TADASHI
IPC: H04N5/335
Filed: 1992-07-15
Abstract: PURPOSE:To reduce an amplification noise after multiplication and to obtain a high sensitive photographic element by applying avalanche multiplication to a signal charge. CONSTITUTION:This device is to diffuse P-type and N-type impurity to both poles and to form a Pin diode 113 by removing conventional source-follower amplifier and reset transistor and forming an i-type semiconductor on a floating diffusion FD 112. The signal charge is inputted to the FD 112 via a charge transfer path 111. The signal charge transferred to the FD 112 is introduced to an i-type area by the Pin diode 113, and the avalanche multiplication is applied to it in the i-type area by supplying a bias voltage sufficiently. The amplifier noise after the avalanche multiplication can be reduced to 1/M by outputting the signal charge after applying the avalanche multiplication by M times in such way. Also, since a noise by the avalanche multiplication is proportional to a signal, the noise in a small signal can be reduced.

Abstract: PURPOSE:To remove an unpleasant feeling due to a white noise at the time of setting a coefficient by comparing a temperature at the time of disconnecting a power source with the temperature at the time of throwing the power source, and correcting an echo canceler coefficient according to the result. CONSTITUTION:The interior temperature of a terminal 5 is measured by a temperature measuring equipment 17 at the time of disconnecting the power source, and the measured result is stored in a temperature storage memory 15. And also, the echo canceler coefficient is stored in a coefficient memory 13.

Then, the result is compared with a value in the memory 15 by a temperature comparator 16, and the coefficient in the memory 13 is multiplied by a preliminarily set constant by a multiplier 14 according to a temperature difference in order to correct the coefficient. Then, the multiplied result is substituted in the echo canceler coefficient setting area of an echo canceler 11. Thus, a state capable of an echo cancel can be attained immediately at the time of throwing the power source, so that a learning due to the white noise can be unnecessitated.
