This paper analyzes the nonlinearity of TDC (Time-to-Digital Converter) used in wireless bearing angle measure system by using INL (Integral Non-Linearity) and DNL (Differential Non-Linearity) specification. Nonlinearity can be represented by the distance error, which indicates the uncertainty of the angle and position in this system. We investigate the distance error based on INL and cause of nonlinearity from the viewpoint of layout. We compare pre and post layout simulations of parasitic resistance in metal power line, describing important layout points to keep in mind. Jitter and mismatch simulation are proposed for setting delay buffer size and TDC time resolution. Wire bonding inductance simulation is also considered for checking robust circuit operation. Verified TDC is an 8bit with a 18ps resolution. The measured DNL and INL were 0.8 LSB and -15 LSB. Samsung 65nm process was used.
