Abstract
Architecture for supporting ZIF or LIF/IF systems includes 4N pins, 2N ADCs, a determination unit and a processing unit, N being a positive integer. The 2N ADCs include a y-th ADC for converting a differential analog signal received by a (2y−1)-th pin and a 2y-th pin into a y-th digital signal, y being positive integers ranging from 1 to 2N. The determination unit determines whether the digital signals are ZIF signals, LIF signals or IF signals. The processing unit performs an ZIF system processing on the ZIF signals, performs a LIF system processing on the LIF signals, and performs an IF system processing on the IF signals.

Architecture for supporting zero intermediate frequency (ZIF) or low intermediate frequency (LIF)/intermediate frequency (IF) systems, comprising:
- 4N pins, N being a positive integer;
- 2N analog to digital converters (ADCs), comprising a y-th ADC for converting a differential analog signal, received by a (2y−1)-th pin and a 2y-th pin of the pins, into a y-th digital signal, y being positive integers ranging from 1 to 2N;
- a determination unit for determining whether the digital signals are ZIF signals, LIF signals or IF signals;
- and
- a processing unit for performing an ZIF system processing on the ZIF signals, performing a LIF system processing on the LIF signals, and performing an IF system processing on the IF signals.
A method for supporting ZIF or LIF/IF systems, applied to architecture for supporting ZIF or LIF/IF systems, which comprises 4N pins, 2N ADCs, a determination unit and a processing unit, N being a positive integer, the method comprising:
- converting a differential analog signal, received by a (2y−1)-th pin and a 2y-th pin of the pins, into a y-th digital signal by a y-th ADC of the 2N ADCs, y being positive integers ranging from 1 to 2N;
- determining whether the digital signals are ZIF signals, LIF signals or IF signals by the determination unit;
- and
- performing an ZIF system processing on the ZIF signals, performing a LIF system processing on the LIF signals, and performing an IF system processing on the IF signals by the processing unit.
