Title: Broad band balanced output circuit
Inventor: NOBEMOTO KAZUO
IPC: H03G3/02
Filed: 1988-06-27
Abstract: PURPOSE:To eliminate the need for the provision of a negative bias power supply circuit by providing an impedance element causing a forward voltage drop to control an output voltage of each transistor(TR) zero or negative. CONSTITUTION:Bases of three TRs 1-3 corresponding to R, G, B demodulation circuits for CRT display are connected to a control input circuit 19 able to change the level of the control input over a wide range. With the TRs 1-3 operated with the reception of the control input, diodes 10-12 decrease the anode- cathode voltage by their forward voltage drops independently of the forward current. Thus, the bias is set so that the output potential of the TRs 1-3 is decreased to zero or a negative value without provision of any negative bias power supply, resulting that even if the level of the control input is varied over a wide range, each output potential is varied while its ratio is always kept constant.

Abstract: PURPOSE:To prevent the deterioration in the picture quality due to clock leakage, by utilizing a picture signal read out from a storage section storing picture signals obtained at an image pickup section using a solid-sate image pickup element and a picture signal obtained at the image pickup so as to suppress the noise of the picture signal. CONSTITUTION:A charge stored in the image pickup section 1 is added for two- cells' share vertically in the vertical blanking period at exposure and transferred and stored in a storage section 3. The charge is read out at the 1st horizontal transfer from the storage section 3 for each one horizontal synchronizing period at the next one field period. On the other hand, a charge corresponding to a dark current of the image pickup section 1 shut at the same time is added for 2-cells' share veritcally, it is read out from the 2nd horizontal transfer register 2 and injected to the 1st horizontal transfer register 4 from the charge injecting section 12 with inversion 11. When the injection for 1H is finished, the charge stored on one row of the lowermost part of the storage section 3 is transferred to the register 4. Then, the charge is added to the charge injected from the injecting section 12. Thus, the charge read out from the register 4 is eliminated for unnecessary signals such as clock leakage and dark current.
