Title:
アナログ・デジタル変換器およびアナログ・デジタル変換器のための中間コードを発生する方法
Document Type and Number:
Japanese Patent JP4027895
Kind Code:
B2
Abstract:
Analog-to-digital converter for converting an analog input signal into a digital binary output signal includes a reference unit for generating a thermometric signal based on comparison of the input signal with a reference voltage level, a first logic circuit connected to the reference unit for generating an intermediate signal based on the thermometric signal, and a second logic circuit connected to the first logic circuit for generating the digital binary output signal based on the intermediate signal. The thermometric signal includes a bit word from a first set of bit words and the intermediate signal includes a bit word from a second set of bit words. Bit words from the second set are arranged in rows of a matrix, the sequence of the rows corresponding to unique numbers represented by the bit words. Respective numbers of bit changes in the respective columns of the matrix are at least substantially equal.
