It consists of 64 flip-flop sensors, each of which contains two phototransistors with different light sensitivity. Each flip-flop sensor senses the light intensity and converts it to a series of \"one\" s and \"zero\"s. It is operated by turning on and off the supply current with a high frequency. During absence of light the flip-flop is totally symmetrical and as a result the number of \"one\"s and \"zero\"s is equal. Light causes an asymmetry in the flip-flop that changes the ratio of \"one\"s and \"zero\"s. A fully digital output is obtained by counting the number of \"one\"s. A triangle wave voltage is applied to the flip-flop in order to vary the threshold of the flip-flop. The device showed that a large array of sensors with on-spot A/D conversion can be realized using the flip-flop sensor technique.","PeriodicalId":197244,"journal":{"name":"ESSCIRC '88: Fourteenth European Solid-State Circuits Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125746841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
