Jitter-Based Reconstruction of Transmission Line Pulse using On-Chip Sensor

A technique for reconstruction of on-chip high frequency signals is demonstrated. The majority of the on-chip reconstruction methods based on subsampling technique are applicable to synchronized systems. This paper demonstrates a jitter-based subsampling technique for non-intrusive reconstruction of on-chip high frequency signals in nonsynchronized systems. The proposed technique is demonstrated on a custom designed IC in 180 nm technology. The on-chip sensors are used for acquisition of high frequency signals as a response to the transmission line pulses (TLP) applied to the IC. The presented technique is also used to investigate the influence of the TLP on the internal nodes of the IC.
