FAN-OUT BUFFER WITH SKEW CONTROL FUNCTION, OPERATING METHOD THEREOF, AND PROBE CARD INCLUDING THE SAME - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18075542 Titled 'FAN-OUT BUFFER WITH SKEW CONTROL FUNCTION, OPERATING METHOD THEREOF, AND PROBE CARD INCLUDING THE SAME'
Simplified Explanation
The abstract describes a fan-out buffer that includes multiple channels with delay circuits to adjust the delay time of a calibration test signal. The buffer also includes edge-to-pulse converters to detect edges in a time domain reflectometry waveform and generate start pulse signals. Additionally, there is a stop pulse signal generator and a delay control signal generator to calculate phase differences and generate delay control signals. The purpose of this buffer is to provide accurate timing control for signals in a circuit.
Original Abstract Submitted
Disclosed is a fan-out buffer which includes a first channel that includes a first delay circuit adjusting a first delay time of a calibration test signal depending on a first delay control signal, a second channel that includes a second delay circuit adjusting a second delay time of the calibration test signal depending on a second delay control signal, a first edge-to-pulse converter that detects a first edge included in a first time domain reflectometry (TDR) waveform of an output terminal of the first channel and generates a first start pulse signal including a first pulse, a second edge-to-pulse converter that generates a second start pulse signal including a second pulse, a stop pulse signal generator that generates a stop pulse signal including a first stop pulse, and a first delay control signal generator that calculates a phase difference generates the first delay control signal.
