Title: Level shift circuit and its driving method
Inventor: ISHIHARA TSUTOMU
IPC: H01L29/762
Filed: 1979-09-11
Abstract: PURPOSE:To improve degradation of the low-frequency characteristic accompanied with level shift, by using the DC differential amplifying action of an operational amplifier to shift the DC level of an input signal. CONSTITUTION:The signal from signal source 31 is output through switches 23 and 24 and operational amplifier 20 having constant-voltage supply circuit 26. At this time, switch 23 is closed to charge capacitor 21, and after that, switch 23 is opened to store and hold the sampling value of the input signal in capacitor 21. Next, switch 24 is closed to output the signal voltage, which is superposed to the DC voltage, from operational amplifier 20. In this case, the sampling value is transmitted as it is, and only the DC level is shifted by 2VB (the voltage of circuit 26), so that degradation of the low-frequency characteristic accompanied with level shift can be improved.

Abstract: PURPOSE:To prevent the deterioration of the region located in the vicinity of a resonant surface due to concentration of energy by a method wherein the active layer located in the vicinity of the resonant surface is formed thicker than the other part, thereby enabling to reduce the energy density there. CONSTITUTION:A stripe-like convexity 4 is formed in the center part of a semiconductor substrate 1 and the first clad layer 5, having tapers 6 and 7 toward the direction of resonant surfaces 2 and 3, is provided above said convexity 4. Above the first clad layer 5, an active layer 8 having a band gap smaller than the first clad layer and a high refractive index of light, the second clad layer 9, a cap layer 10 and an electrode 11 are laminated successively. As a result, the thickness of the clad layer 5 is increased in the vicinity of the tapers 6 and 7, thereby enabling to concentrate the applied current at the convexity 4, and almost no current is flowing to the tapers 6 and 7. Accordingly, the energy concentration at the part in the vicinity of the resonant surfaces 2 and 3 can be suppressed, and the deterioration at this part can be prevented. Also, as the expansion angle of the beam is reduced when compared with that of the conventional product, a laser beam having a high coefficient of true roundness can be obtained.
