【発明の名称】時間/電圧変換方法及び装置
Document Type and Number:
Japanese Patent JP3231318
Kind Code:
B2
Abstract:
1. A system consisting of a method and a preferred device suitable for carrying out the method according to the invention for time/voltage conversion is presented which determines voltage values which correspond to the duration of pulses. 2.1 Known systems of the type mentioned have inaccuracies in the time/voltage conversion as a result of which nonlinearities occur. 2.2 To avoid nonlinearities in the conversion, voltages of pulses, the duration of which is used for time/voltage conversion, are matched according to the invention to the variation of an auxiliary voltage which is used for forming an output voltage. This auxiliary voltage can be a ramp voltage emitted by a ramp voltage generator, or any other voltage which is present at the components of the device according to the invention. 2.3 The system according to the invention can be preferably used as part of an amplifier device which is constructed in thin-film technique and is used for driving a liquid-crystal display. 3.
