| Abstract: |
Employing an updated C²MOS technique, two types of speech synthesizer LSI circuits, based on the PARCOR and the ADM methods,
are introduced and described.
These two LSI circuits, fabricated with a standard metal gate CMOS process, have several features.
1) They can be operated with a single power supply over a 3-7 V range.
2) Their power dissipations are, respectively, 0.6 mW (PARCOR) and 0.18 mW (ADM) with the supply at 3 V.
3) High accuracy 9- and 10-bit R, 2R D/A converters are constructed in each LSI circuit.
In the PARCOR system, various high quality and low data rate speech outputs are obtainable. The ADM system is used for voice
transmission and synthesis. By adequately applying these two systems to the wide needs in the market, it is possible to achieve
good cost performance. |

| Abstract: |
This paper will cover two speech synthesizer LSIs developed in C²MOS technology. One uses the partial autocorrelation
(Parcor) algorithm and the other is based on adaptive delta modulation. The power dissipation is only 0.6 and 0.18mW, respectively. |
