Abstract:
Systems and methods for direct digital synthesis are disclosed. A direct digital synthesis system includes a direct digital synthesizer (DDS) and a programmable logic device (PLD) configured to control the DDS. The DDS includes at least one digital analog converter (DAC) and a coupled driver/buffer configured to drive relatively high capacitive loads with substantially rail to rail sinusoidal driver output signals and with little to no waveform distortion. The DAC includes a PMOS DAC and an NMOS DAC and a switch configured to select the PMOS DAC for negative portions and the NMOS DAC for positive portions of an output analog signal generated by the DAC. The driver includes a pair of input differential amplifiers, PMOS and NMOS transistor structures, which may be variable, and a pair of variable current sources. The PLD is configured to control variable elements of the DDS to adjust the achievable positive and negative slew rates of the DDS, independently of one another, to reduce or eliminate risk of signal distortion while maintaining substantially stable rail to rail output.

Claim (Index 14):
The system of  claim 13 , wherein:\n the driver is configured to generate an output driver signal based on the corresponding analog signal provided by the DAC and provide the output driver signal to a sensor system; and the PLD is configured to receive sensor signals from the sensor system, corresponding to the output driver signal, and process the sensor signals to measure and/or detect an event sensed by the sensor system.
