try this one

if (window.addEventListener) window.addEventListener('DOMMouseScroll', wheel, false);
window.onmousewheel = document.onmousewheel = wheel;

function wheel(event) {
    var delta = 0;
    if (event.wheelDelta) delta = event.wheelDelta / 120;
    else if (event.detail) delta = -event.detail / 3;

    handle(delta);
    if (event.preventDefault) event.preventDefault();
    event.returnValue = false;
}

function handle(delta) {
    var time = 1000;
    var distance = 300;

    $('html, body').stop().animate({
        scrollTop: $(window).scrollTop() - (distance * delta)
    }, time );
}

First make a link with #top link then try the following code try this

<script type="text/javascript">
$("a[href='#top']").click(function() {
  $("html, body").animate({ scrollTop: 0 }, 1000);//here you can specify your time for smooth operation
  return false;
});
</script>
