Abstract :
A CMOS time-to-digital converter chip, the time memory cell (TMC), for high-rate wire chamber application has been developed. The chip has a timing resolution of 0.52 ns, dissipates only 7 mW/channel, and contains four channels in a chip. Each channel has 1024 memory locations which act as a buffer 1- mu s deep. The chip was fabricated in a 0.8- mu m CMOS process and is 5.0 mm by 5.6 mm. A CAMAC module with 32 input channels was developed using the TMC chip. This module is designed to operate in both common start and common stop modes. The circuit of the module and test results are described.<>
