Abstract
Systems and methods provide architectures for various applications, for example, for software defined radios and other high frequency (HF) application. Embodiments can provide novel multi path ΣΔ architectures that form the basis for novel N path Sigma Delta (NΣΔ) modulators, NΣΔ digital to analog converters (NΣΔ DAC) and NΣΔ analog to digital converters (NΣΔ ADC).

A multi-path sigma delta modulator comprising:
- an N-path down converter configured to receive a high frequency input signal, the N-path down converter comprising a plurality of signal propagation paths;
- wherein each signal propagation path comprises:
- a filter configured to filter a signal passing through the respective signal propagation path;
- and
- a quantizer coupled to the filter configured to generate a digital path output;
- and
- a digital decimation filter coupled to the quantizers of the plurality of signal propagation paths, the digital decimation filter configured to combine the digital path outputs to generate a digital output signal.

A multi-path sigma delta modulator comprising:
- an N-path down converter configured to receive an input signal, the N-path down converter comprising a plurality of paths configured to filter and scale the combined input signal to generate a down-converted analog signal;
- and
- a quantizer configured to digitize the down-converted analog signal to generate a digital output signal.
A method for generating a digital output signal from a high frequency input signal, the method comprising:
- receiving, by an N-path down converter, the high frequency input signal, wherein the N-path down converter comprises a plurality of signal propagation paths;
- filtering, by a filter in each of the plurality of signal propagation paths, a signal passing through the respective signal propagation path;
- generating, by a quantizer coupled to the filter in each of the plurality of signal propagation paths, a digital path output;
- and
- combining, by a digital decimation filter, the digital path outputs to generate the digital output signal.
