yc_2 Posted June 14, 2004 Report Share Posted June 14, 2004 If I want to design a Switched-Capacitor Digital to Analog Converter front-end transmitter for CDMA application, can someone tell me where can I get the information about the design. (like the theory that involved, schematic, etc)Thanks Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted June 17, 2004 Report Share Posted June 17, 2004 The idea of a D/A is surrounded by the weighted ladder. Each sequence is able to produce a current that results in a voltage. But I am wary of this opamp configuration because of how it is used. The opamp is meant to operate high gain, even though it will operate as a constant current source. I would be tempted to change the configuration a little. You could probably use a transistor circuit and achieve what you want. Quote Link to comment Share on other sites More sharing options...
