Abstract
Embodiments relate to a waveform processing device. The device can include a first input node configured to receive a first signal and a second input node configured to receive a second signal. The device can include a pulse generator including a self-timed digital converter (DTC) with a clock generator (CLK). The device can include a switching network configured to be driven by an output from the pulse generator to modulate the first signal and the second signal in synchronization.
Claims20
A waveform processing device, comprising:
- a first input node configured to receive a first signal having a first time-varying waveform;
- a second input node configured to receive a second signal having a second time-varying waveform;
- a pulse generator including a self-timed digital converter (DTC) with a clock generator (CLK);
- and
- a switching network configured to be driven by an output from the pulse generator to modulate the first signal and the second signal in synchronization.
A waveform processing device, comprising:
- a first input node configured to receive a first signal, wherein the first input node includes a first digital to analog converter (DAC) configured to generate a voltage V1 based on the first signal;
- and
- a second input node configured to receive a second signal, wherein the second input node includes a second DAC configured to generate a voltage V2 based on the second signal;
- a pulse generator including a self-timed digital time converter (DTC) with a clock generator (CLK) and a reset/set (R/S) latch;
- and
- a switching network including a switch driver, a first switch connected to an output of the first DAC, and a second switch connected to an output of the second DAC, wherein the switching network is configured to be driven by an output from the pulse generator to modulate the first signal and the second signal in synchronization.
A method for synchronizing waveforms, the method comprising:
- receiving a first signal, having a first time-varying waveform, at a first input node of a waveform processing circuit and a second signal, having a second time-varying waveform, at a second input node of the waveform processing circuit, the waveform processing circuit including:
- a pulse generator with a self-timed digital time converter (DTC) with a clock generator (CLK);
- and a switching network connected to the pulse generator;
- and
- driving the switching network by an output of the pulse generator to modulate signals received by the waveform processing circuit in synchronization.
