The high luminosity LHC designed for the peak luminosity of $7\times 10^{34}~{\rm cm}^{^2}{\rm s}^{-1}$
and integrated luminosity of $3000~{\rm fb}^{-1}$ is scheduled from 2026.
The trigger and readout system of the ATLAS detector is also upgraded to cope with the increased latency and the increased first level trigger rate.
The sophisticated tracking-based muon trigger algorithm with the Thin Gap Chamber (TGC) and the Monitored Drift Tube detector (MDT)
is introduced in the end-cap first level muon trigger to improve the momentum resolution in the hardware level.
Sending all hit information from the on-detector electronics to the off-detector electronics in the counting room allows us to make sophisticated tracking trigger algorithm.
The developments of the TGC front end board and the MDT mezzanine cards are keys of the tracking-based trigger.
In this paper, the developments of the end-cap muon trigger electronics, in particular the developments of the font-end electronics, are reported.
