He told BBC Radio Leicester: "I've not really been given the opportunity to play in the top flight.
"I'm desperate to achieve my goal and that's why I came to Leicester."
Brown played 41 league games for the Tigers in their promotion season, with their place in the top flight being secured with a 1-0 win over Bristol City in the Championship play-off final at Wembley.
But the 32-year-old centre-half's dream was shattered after just one game, a distinctly forgettable 5-0 thumping at the hands of Wigan.
The former Ipswich, Watford and Colchester man was allowed to go out on loan, eventually signing permanently for Nigel Pearson's Leicester in April last year after a successful temporary stay.
Since then Brown has been instrumental in helping the team climb from League One to the verge of the Premier League, winning praise from Pearson and less experienced team-mates like Jack Hobbs.
But now he wants to make up for lost time - and said he is not daunted by the prospect of facing players of the calibre of Didier Drogba, Wayne Rooney and Fernando Torres.
"This is why you're in the game," Brown said. "You want to play in the big arenas against the best teams and players in the world and as yet I haven't had the opportunity to do that.
"I firmly felt there was the potential at this club and the ambition from the manager and the chairman to reach the Premier League - let's hope I can do it this season."
Cardiff finished fourth in the regular season but Brown is not too concerned about the opposition and is relishing the challenge of a two-legged semi-final.
"These occasions are superb to play in - this is why you're in the game," Brown said.
"You want to play in big arenas and big atmospheres but if you think about the occasion you won't do that well. We have to see it as another game.
"When you come back at the start of the season this is your aim - you want to get promotion and we will have to do it via the play-offs. We have worked hard all season and we are not going to give it up lightly now.
"Cardiff are a good side and will be a tough fixture. We've done our homework on them but we will be concentrating on us - not what Cardiff can do to us but what we can do to them.
"And if we do that and we do cause them problems - which we will - then we shouldn't have a problem."
Midfielder Andy King is also eager to get the play-off campaign up and running and says their superb five-game winning run at the end of the regular season means they approach Sunday's match full of confidence.
King itching to start play-off campaign
"Excitement is the main felling around the place," King said. "We just want to get the game underway now. We've prepared right, we're in a good run of form and looking forward to it.
"We had another good win on Sunday, which kept the momentum going into the semi-finals.
"One of the reasons we've had such a successful year is everyone's hungry to play. There is good competition for places at the club so everyone is fighting for their spot."
