摘要

针对高频开关电源(SMPS)的数字控制器，提出了不采用编码器将“温度计码”转换成二进制码，直接输出二进制码的模数转换器(ADC)架构。它可以提供所需精度的大转换范围，并降低ADC电路的复杂性。输出可以按照对数规律压缩成更短的寻址字符，从而减少了数字补偿器查找表的内存大小

ADC architecture with direct binary output for digital controllers of high-frequency SMPS

Without adopting encoder to convert "thermometer code" into binary code, analog-to-digital converter (ADC) architecture with direct binary code output is proposed for digital controllers of high-frequency switching mode power supply (SMPS). It can provide large conversion ranges with required precision and reduce ADC circuit complexity. The output can be compressed into a much shorter addressing character in logarithmic law and lead to reduction of memory size in the look-up table of the digital compensator
