- Abstract
- Coverage expandable current type code controlled DCC is presented, which has TDC-based range selector. The TDC-based range selector is composed of the TDC, the anti-harmonic lock block and the encoder/decoder. The code controlled current source has asymmetric current source to both current sinks for duty error correction and is controlled by binary digital codes. And the DCC amplifier controlled by binary codes has switches which are selected according to the input frequency range. With the frequency range information, the DCC amp can expand the cover range with suitable bit resolutions. The proposed circuit is designed and simulated with 54nm CMOS technology. The DCC circuit can correct at least duty error of 6% from 500 MHz through 1.25 GHz.
