摘要 |
In a PCM CODEC, a binary-weighted charge redistribution capacitor array is designed to be configured for either mu -law or A-law coding. Selection of one or the other coding configuration is achieved by controlling a single gate circuit. A unique cascaded switch arrangement ensures that when selected capacitors representative of a specified coding segment are connected to a reference voltage source, the next successive capacitor of the array is automatically connected to a variable source that provides a voltage representative of a step within the specified segment. |
