I am using the following circuit for PWM Dimmer.Please advice what should I do!

I am currently using LM 324 op amp Ic for generating PWM waveforms from a 9 V supply.Do you mean to say that say taht at the output of the MOSFET I just have to have a 200k resistor and a general purpose BC 547 transistor. please advice

I need a 1.2 V PWm Signal To dim my LEDs which I am driving through zetex Part number ZXLD1350.The Dc dimming they have proposed is not sufficient for me.Please help me and tel;l me so as how to generate PWm signal having duty cycle of 1.2 V
