Digitally Tuned Bandpass Sigma Delta Modulator for Wireless Communications

Continuous compensation of binary-weighted DAC nonlinearities in bandpass delta-sigma modulators

“…relatively easy to achieve. While recent implementations for specific applications 20 still use 1-bit quantizers [20][21][22], the majority of recently reported AS modulators use multibit quantization [23][24][25][26][27][28][29].…”
