A differential switched capacitor digital-to-analogue (DAC) circuit ( 500 ) comprises first and second differential signal circuit portions ( 500 a,b ) for providing respective positive and negative signal outputs with respect to a reference level, and has first and second reference voltage inputs...
Digital to analog converting circuit A multi-channel DAC having a digital input port () for receiving digital input codes and a plurality of analogue output terminals (OUTto OUTN) on channels (CHto CHN) on which corresponding analogue signals are outputted, comprises a prim... D Geraghty,P...
When the input bit associated with any resistor is equal to 0, that resistor is not switched into the circuit but instead is replaced by a short circuit of zero resistance. To produce an analogue output voltage, all that is then necessary is to drive a certain standard but constant current...
Disclosed is a structure of an eight channel high-accuracy synchronous sampling analog-to-digital conversion circuit. In the current high-accuracy sampling technique, some automatic measurement and control devices are inconvenient due to the lack of channels of the synchronous sampling. The utility ...
An N-bit DAC comprises a main DAC circuit having main nodes on which analogue voltages are produced of progressively increasing values in steps of the value of one MSB value, and a sub-DAC circuit having secondary nodes on which analogue voltages are produced of progressively increasing values ...
Probably more important is that the circuit designer now doesn't have to concern himself with the accuracy of several parts in a system. The system is now one part and tested by the manufacturer as a unit. Next we will look at the various DAC architectures. When we refer to DACs here ...
