Decimatorless continuous-time delta-sigma analog-to-digital receiver

A decimatorless continuous-time delta-sigma analog-to-digital receiver, comprising:

• a continuous-time delta-sigma modulator (CTDSM) that receives a receiving signal and is configured to encode analog signals into digital signals;
• and
• a demodulator that receives a digital output of the CTDSM and is configured to recover information content from the receiving signal;
• wherein no decimator is used to down convert a sampling rate of the receiving signal;
• wherein the CTDSM itself possesses a low-pass filtering function and thus no low-pass filter is required to precede the CTDSM;
• and
• wherein the demodulator works at a frequency that is at least higher than a cut-off frequency of the low-pass filtering function.
