Abstract :
A CMOS time to digital converter (TDC) chip with wide dynamic range, high resolution and ability to accept input asynchronous to the time reference (external clock) is discussed. The system presents low power dissipation, small processing time and an adjustable range and measurement step. The chip is intended for laser altimetry and particle detection and recognition instruments in scientific space missions.
