Abstract :
A single chip speech synthesizer was designed using a switched-capacitor multiplier to implement the LPC algorithm. The chip contains the LPC-10 filter, 20 kbit ROM, all control logic, a three-pole switched-capacitor low-pass filter, and an audio amplifier capable of driving a speaker directly. The chip was fabricated in 5 µm CMOS technology and is 218 mils on the side.
