Title: Chopper amplifying circuit
Inventor: OONISHI MAKOTO
IPC: H03F3/38
Filed: 1982-01-29
Abstract: PURPOSE:To reduce the offset and 1/f noise of a switched capacitor circuit, by providing a switch circuit to invert the polarity of the signal that is applied to the switched capacitor and actuating the switch of an output circuit in response to the driving signal of the switch circuit. CONSTITUTION:Switches SW1 and SW4 are closed by a pulse phi1 during a period T1 to charge the input voltage Vin to a capacitor 1, and at the same time a capacitor 2 is discharged by a pulse phi13. The electric charge of the capacitor 1 is shifted to the capacitor 2 by a pulse phi24 in a period T2, and at the same time the output voltage is charged to the capacitor 2 by a pulse phi2. In a period of T3 the capacitor 2 is discharged, and the output voltage Vout of a capacitor 3 is delivered. In a period T4 the output voltage having the polarity opposite to that obtained in the T2 is charged to the capacitor 3. These above-mentioned operations cover a period of a chopper, and the signal component and the offset voltage are turned into a component converted into a chopper frequency component to the input shown in a figure (a). This component is deleted through an LPF to erase the offset voltage.

Title: Ac amplifying circuit
Inventor: SATOU AKIRA
IPC: H03F3/34
Filed: 1982-01-29
Abstract: PURPOSE:To obtain an AC amplifying circuit having a short saturation time, by connecting a switch to a DC cut-off capacitor to quick charge and discharge. CONSTITUTION:Electronic switches S1 and S2 and an AC/DC converter 1 are actuated by timing signals (d), (e) and (f) supplied from a switch driving circuit 3. The switches S1 and S2 repeat periodical ON/OFF operations opposite to each other. When the S1 is turned on, a capacitor C is quickly charged or discharged. Therefore the DC component of a signal (b) of the 2nd stage is immediately set at 0, and the saturation time of an amplifier A2 due to the DC component is greatly reduced. In this case, the AC component of the signal (b) is also set at O when the switch S1 is on, and the amplifier A2 is reset to a normal operation much quicker than conventional. Here the switch S2 is turned off simultaneously with the ON of the S1 to keep the final output (g) at a level obtained immediately before the S1 is turned on. Thus the output fluctuation is suppressed. The S2 is turned on when the S1 is turned off, and the normal output is obtained.

Title: Synchronization detection circuit
Inventor: TERADA YOSHITAKA
IPC: H04N1/04
Filed: 1991-02-01
Abstract: PURPOSE:To prevent malfunction due to noise and to keep a synchronization timing constant even at fluctuation of luminous quantity by bringing a level of one output of two photoelectric conversion elements when no optical beam is made incident forcibly to a prescribed clamp level. CONSTITUTION:Photodiodes PD1, PD2 are arranged in cascade in the beam scanning direction and an optical current output is subject to amplification and I/V conversion by amplifiers A1, A2 to obtain voltages V1, V2. The voltage V2 is inputted to a lower limit clamp circuit 5, which clamps a level when no optical beam is made incident to a prescribed level V21. Then the level V21 is set higher than a predicted noise level, the voltage is inputted to a comparator 6 together with the voltage V1 and the voltages V1 and V21 are compared to obtain a synchronization timing V0 representing the scanning timing. Thus, malfunction due to noise is prevented and the level V21 is set to obtain a cross point with respect to the voltage V1 and V21 even when the incident luminous quantity is low thereby keeping the cross point due to luminous quantity fluctuation, that is, the synchronization timing constant.
