CONCLUSIONS

This project involved the design of a Class-D Audio Amplifier circuit involving the complete IC Design flow from concept to GDS to testing. The important features for the chip can be seen in the table below.

Feature Value
Switching frequency 280KHz - 380 KHz
Input frequency 20 Hz to 20 KHz
Operating voltage range 1.2 V
Total Harmonic Distortion -47.67 dB (@Fs = 369.9 KHz; Vin = 200mV)
Power Efficiency 81.12% (@Fs = 369.9 KHz; Vin = 200mV)
