A high‐speed, large dynamic range f S /4 bandpass ΔΣ‐modulator using a first‐order error‐feedback loop is proposed. The internal quantiser is realised using a high‐speed pipelined ADC. Error feedback is achieved by exploiting the implicit latency in a pipelined ADC. The proposed architecture achieves an SNR of 94 dB with an OSR of 32.
