  In this note we examine the circular time-like geodesics near a spherically
symmetric dilaton black hole, described using the exact solution for a static
charged black hole found by Gibbons and Maeda and, independently, by Garfinkle,
Horowitz and Strominger. The existence and stability of the circular orbits are
analysed using the effective potential of a free material test particle moving
on time-like geodesic near this black hole. We determine the radius of the
innermost stable circular orbit, the radius of the shortest circular orbit and
compare our results with those obtained by other authors for specific values of
the parameters involved in our analysis.
