Abstract :
In this paper we utilize the novel digital techniques (TW, DRMC, DS) to improve the sensitivity of the limiting amplifier. The Time Window (TW) technique can ignore the positive and negative trigger noises within the window close time. The Delay Racing Memory Counter (DRMC) technique can eliminate the positive trigger noises within the window open time. The Delay Sum (DS) technique can solve the negative trigger noise around the signal transition from low to high. The experimental results are also presented
