DSP: Z transform style help ....

[flatmax]

Hello there,

I was wondering wether someone could refresh my memory ... 
Z transforms are derived using : exp(-jw) => z^-1, where j is the
sqrt(-1) and w is the same as 2*PI*f where 'f' is a frequency.

I was wondering from memory, the z-transform equivalent of :
-(1/jw) exp(-jw) => -1/dz z^-1

Any takers ?

thanks
Matt
