High-Resolution IF-to-Baseband SigmaDelta ADC for Car Radios
High-Resolution IF-to-Baseband SigmaDelta ADC for Car Radios addresses the theory, system level design and circuit implementation of a high-resolution continuous-time IF-to-baseband quadrature SigmaDelta ADC. The target application of this ADC is in AM/FM/IBOC car radios. The ADC achieves a dynamic range of 118dB, which eliminates the need for an IF VGA or AM channel filter in car radios.
Successful design of very high-resolution SD ADCOnly published design combining Switched-capacitor (SC) feedback and IF mixerAchieves high-linearity besides the combination of SC feedback and IF mixerOnly IF ADC to allow elimination of VGA and AM filter from the car radio receiver
