Preface
In the application of PLL, DLL and CDR circuits, people generally require the output clock signal to have a 50% duty cycle so that data can be sampled at both the rising and fallin...[Details]
Portable products are generally powered by batteries. Due to cost and size considerations, there is a trend to reduce the number and size of batteries used in design. If the number of batteries is ...[Details]
1 Introduction
In many communication systems, the base station usually sends a training sequence for the terminal to synchronize with the system. The synchronization here includes time syn...[Details]
Currently, there are huge differences in market analysis statistics for high-brightness LEDs (light-emitting diodes). Despite the divergence of forecasts, one trend is clear: the high-brightness (H...[Details]
