Abstract:
Continuous time sigma delta (ΣΔ) analog-to-digital conversion (ADC) circuitry and method in which current mode ΣΔ ADC circuitry is driven directly by current mode mixing circuitry, thereby avoiding a need for a current-to-voltage driver between the input signal mixing circuitry and ΣΔ ADC circuitry.
