I want to give a 1kHz-2kHz signal to an AND gate. What are the suitable logic gate ICs ?

A frequency range of 1kHZ to 2kHz is not much for the modern day CMOS technology ICs. You can use any gate from the 74HCXX family as these IC's can even operate in range of MHz.

The 74HC08 IC should work perfect for you .

Accurate gate resistance values for large-area power MOSFETs have been obtained from calorimetric power loss measurements. It is shown that advanced power MOSFETs fabricated using refractory silicide gates exhibit a fivefold reduction in the gate resistance compared to conventional power MOSFETs with heavily POCl/sub 3/-doped polysilicon gates. Power MOSFETs with integral Schottky diodes are shown to further reduce the resistive-gate power dissipation. A simple analysis is used to evaluate the switching efficiency of power MOSFETs as a function of output current and switching frequency.
