Abstract
A new method to sample a digital input signal is achieved. The method comprises sampling a digital input processed through a first digital buffer. The sampling is at the rising edge of a system clock. The switching threshold of a second digital buffer is updated. The digital input processed through the second digital buffer is sampled. The sampling is at the falling edge of the system clock. The switching threshold of the first digital buffer is updated. A digital sampling circuit is achieved.
