The 26-year-old striker has netted eight goals since arriving from Montpellier in a £13m deal during the summer.
Although his most recent goal came against Tottenham in mid-November, the Frenchman is feeling confident and upbeat.
Giroud said: "It has been an interesting few months but now I want to do more.
"I am an Arsenal player and rightly expectations are high. I am trying to do what the boss asks of me, to put pressure on defenders and to improve on protecting and holding the ball.
"We put a lot of good crosses in, so it is important that I get on the end of them and score.
"I am feeling better and better in this team all the time. I know my team-mates now and things are more automated on the pitch, which makes things easier for me."
