摘要：A 13-bit, 1.4-MS/s, sixth-order cascaded sigma–delta modulator oversampling at 16 X is implemented in a 0.72 μm complementary metal–oxide–semiconductor process for use in the baseband path of a radio-frequency receiver. The modulator achieves 77 dB of dynamic range and dissipates 81 mW from a 3.3V supply. It is characterized for the blocking and intermodulation requirements of a cordless telephone application.
