(EN) AN ANALOG TO DIGITAL CONVERTER
Abrégé
(EN) THE PRESENT INVENTION RELATES TO AN ANALOG TO DIGITAL CONVERTER (ADC) 100. THE ADC 100 IS COMPRISED OF A QUANTIZER COMPONENT 10 FOR SAMPLING AN INCOMING ANALOG SIGNAL AND GENERATING A DIGITAL SIGNAL; A RESIDUE GENERATOR COMPONENT 20 FOR SAMPLING THE INCOMING ANALOG SIGNAL AND FOR GENERATING A DIGITAL SIGNAL, AND A RESIDUE GENERATOR COMPONENT 20 FOR SAMPLING THE INCOMING ANALOG SIGNAL AND FOR GENERATING A RESIDUAL ANALOG SIGNAL WITH RESPECT TO THE DIGITAL SIGNAL. THE QUANTIZER COMPONENT 10 IS OF A DYNAMIC TYPE WHEREIN NO PREAMPLIFIER IS USED THEREIN AND IS SWITCHABLY CONNECTED TO A SOURCE 110 OF INCOMING ANALOG SIGNALS. THE QUANTIZER COMPONENT 10 IS COMPRISED OF A COMPARATOR CIRCUIT 30 HAVING A PLURALITY OF FIRST TRANSISTORS FOR SUBSTANTIALLY ACTING AS VOLTAGE-CONTROLLED RESISTORS THEREIN, AND A PLURALITY OF SECOND TRANSISTORS FOR SUBSTANTIALLY FORMING A LATCH THEREIN. THE RESIDUE GENERATOR 20 IS SWITCHABLY CONNECTED TO THE SOURCE 110 OF THE INCOMING ANALOG SIGNALS. THE INPUT OF THE RESIDUE GENERATOR COMPONENT IS CONNECTED TO THE OUTPUT OF THE QUANTIZER COMPONENT. THE COMPARATOR CIRCUIT 30 AND THE SWITCHABLE CONNECTION ARE FOR MATCHING THE SAMPLING CHARACTERISTICS OF THE QUANTIZER AND THE RESIDUE GENERATOR COMPONENTS 10 & 20.
