Design of a 1.8-V 14-bit [delta] - [sigma] A/D converter with 8X oversampling and 4 MHz Nyquist output rate

In this dissertation, a new ����� A/D converter is presented that is ideally
suited for communication applications. It is based on a single-loop single-stage
structure, which can realize a high maximum out-of-band quantization noise gain
while maintaining stable operation and thus achieve 14-bit resolution at 8 times
oversampling. A fifth-order ����� analog-to-digital converter (A/D) has been designed
and tested in a 0.18 ��m CMOS process. This is the first single-stage �����
A/D converter reported in the literature that achieves 14-bit resolution at 4 MHz
equivalent Nyquist rate with a 1.8-V power supply. / Graduation date: 2002
