Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To actualize a current mirror circuit nearly up to a threshold voltage even in the case of a rise or fall in the output voltage of a charge pump by including an analog switch which is normally ON in the current mirror, and using the analog switch by turning it ON and OFF while connecting the analog switch in the ON state in the current mirror circuit. SOLUTION: When an UP signal is OFF at UP signal switching time, a contact 8 as the drain terminal of a transistor POFF is at VDD. When the signal turns ON through UP signal switching, the contact 8 comes closer to a contact 7. Then the electric charge migration of parasitic C between the contact 8 and VDD is restricted by a current I. When a DOWN signal is OFF at the time of DOWN signal switching, a contact 9 which is the drain terminal of a transistor NOFF is at GND. When the signal turns ON through DOWN signal switching, the contact 9 comes closer to a contact 3. Then the electric charge migration of parasitic C between the contact 9 and GND is restricted by the current I.

Title: Discharge lamp device
Inventor: KANDA TAKASHI
IPC: H05B41/392
Filed: 1990-08-14
Abstract: PURPOSE:To stably control a lamp current even in a region where the lamp current is small by providing a control circuit in which the OFF-period of a switching device is made almost stable at the time of lighting a discharge lamp, while the ON-period is varied, so as to control the lamp current, and by controlling the lamp current through stabilizing the OFF-period of the switching device. CONSTITUTION:When a resistance value of a variable resistance element VR1 is reduced, the ON-period of a drive signal for turning a switching device SW1 ON, is shortened, and an average value of a lamp current IL is thus narrowed. While an OFF-period is stable, since the ON-period is controlled so as to control the average value of the lamp current IL, the extinguishing of a discharge lamp la hardly occurs, even in a region where an ON-duty is small. Namely, since the OFF-period is stable, restriking is easily generated, and extinguishing hardly occurs for this reason, and the average value of the lamp current IL can be controlled up to where the ON-duty is small, as indicated in the vicinity of a point C. The average value of the current IL, can thus be controlled stably, even in a region where the current IL, is small.
