Design of Program Controlled Function Signal Generator Based on LPC2138

Abstract:

A design of program controlled function signal generator is introduced. LPC2138 is used as a controller to make the adjustment of frequency, waveform and amplitude programmable. We control the frequency by switching the capacitance and setting the input current of MAX038. We used DS1267 to control the amplitude of output signal with high-speed FET-Input operational amplifier OPA132. Our system is equipped with a keyboard and a LCD screen. We used EEPROM memory chip FM25CL16 to save and load waveform parameters. The circuit works well and the output waveform is stable and reliable.
