  The CLIC Tracker Detector (CLICTD) is a monolithic pixelated sensor chip
produced in a $180$ nm imaging CMOS process built on a high-resistivity
epitaxial layer. The chip, designed in the context of the CLIC tracking
detector study, comprises a matrix of ${16\times128}$ elongated pixels, each
measuring ${300\times30}$ $\mu$m$^2$. To ensure prompt charge collection, every
elongated pixel is segmented in eight sub-pixels, each containing a collection
diode and a separate analog front-end. A simultaneous $8$-bit time measurement
with $10$ ns time bins and $5$-bit energy measurement with programmable range
is performed in the on-pixel digital logic. The main design aspects as well as
the first results from laboratory measurements with the CLICTD chip are
presented.
