The present invention relates to pulse power technology. The system includes an input channel, a pulse edge detector (2) connected in series with two inputs, a filter (3), a variable delay unit (4), and a feedback channel from the generator to one of the inputs of the pulse edge detector (2). The system comprises a reference delay unit (1), and the input channel is connected both to the variable delay unit (4) and to a reference delay unit (1) for simultaneous supply of input to said units. Signals to both inputs of the pulse edge detector (2) are synchronous on average, i.e. tstab.avg=1/τ∫ tstab dt=tref with τ>>τest.oper where: tstab.avg—generator output delay relative to the input signal, averaged over the operation time of the system τ at a given tref; tref—reference unit (1) output delay relative to the input signal; τest.oper—stabilization system time response to changes in external parameters, with the stabilization delay tstab determined from the condition tstab=tvar+tunstab where: tvar—delay of the variable delay unit (4); tunstab—unstable delay of the generator. The stabilization of the delay is independent of the pulse repetition frequency.

A single-ended-to-differential converter for driving an LVDS (Low Voltage Differential Signaling) driving circuit includes a first converting circuit, a second converting circuit, and a controller. The first converting circuit converts an input signal into a first output signal. The first converting circuit has a tunable delay time. The second converting circuit converts the input signal into a second output signal. The second converting circuit has a fixed delay time. The controller generates a first control signal and a second control signal according to the first output signal and the second output signal, so as to adjust the tunable delay time of the first converting circuit.

An apparatus and method for synchronizing a triggered system to a triggering system by tracking the timing of rising and falling edges of a clock signal at the triggered system and using the tracked timing values for phase shift adjustment of a time base at the triggered systems.

An integrated circuit includes a pulse width modulator. The pulse width modulator includes a multiplexer that receives a plurality of data delay signals. Each of the data delay signals is based on a data signal and a respective clock phase signal. The multiplexer includes a first multiplexer stage and a second multiplexer stage. The first multiplexer stage receives all of the data delay signals and has a relatively large delay. The second multiplexer stage receives to output signals from the first multiplexer stage and has a relatively small delay. The second multiplexer stage outputs a pulse width modulation signal that can have a pulse width corresponding to the offset between two adjacent clock phase signals.

Exclusive disjunction logic receives the second data and operates on the first data and the second data to generate output data.
