碩士 === 國立交通大學 === 光電(科學)研究所 === 82 === Two driver circuits , one is the voltage-controlled current source suitable for the off-chip operation and one is the current copier suitable for the on-chip operation , for Feild Emission Display ( FED ) have been designed and studied in this thesis. The proposed current source driver circuit can overcome the unstable characteristic of FED . The voltage- controlled current source is composed of a variable resistor and a current mirror which can accurately control the emission current . The emission current response is nearly independent of the large gate- cathode capacitance (typically 5pF) of FED. The gray level can be implemented by the amplitude modulation . The brightness contrast can be adjusted by varying the bias voltage. The current copier makes practical current copies without the need for accurately matched components for the on-chip FED driver . An analysis of the clock feedthrough in this circuit has been made . Several results which are different from the general switch circuits are obtained. A clock feedthrough compensated current copier by using the compensating effect of the gate- drain overlap capacitance has been designed and the addressing for the on-chip driver IC by utilizing this circuit has also been proposed .
