Enhanced integrated waveshaping circuit |
摘要 |
The waveshaping functions provided by a summing resistor network and filter are performed by a waveshaping circuit that can be integrated with transceiving functions within a single integrated circuit. The waveshaping circuit utilizes the edges of an oscillator signal to generate a series of pairs of logic signals which have a defined timing relationship with respect to an input data signal. Each pair of logic signals is then utilized by a corresponding number of current stages to provide both an incremental portion of an output waveform and an incremental portion of a complementary output waveform. The pair of output waveforms can then be produced by summing together all of the incremental portions of the pair of waveforms.
