Such a device includes a light sensing circuit and a conversion circuit. The light sensing circuit generates an induced current signal based on the variations of the intensity of light irradiation received as caused by a touch-control-position event; and the conversion circuit is connected to the light sensing circuit and receives an induced current derived therefrom. The conversion circuit is provided with a first transistor and a second transistor coupled together, that are driven by a positive and a negative biases having the same period but different phases, thus the induced current signals are converted into induced voltage signals based on the alternative turn-on's and turn-off's of the first transistor and the second transistor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Embedded optical induction input device and method of implementing the same","description":"An embedded optical induction input device and method of implementing the same.
