چکیده
An 8bit two-step time-to-digital converter (TDC) with a novel digital switched ringoscillator based time amplifier (TA) is demonstrated in 65nm CMOS. The proposed TA achieves a predictable and programmable gain without requiring any calibration. The implemented 8bit two-step TDC with a 16x TA gain achieves a time resolution of 2.6ps at 80MS/s conversion rate while consuming 2mW. The measured DNL and INL are 1.84LSB and 2.36LSB, respectively. The TDC area is 0.07mm.

Modeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO
The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...
متن کاملMOCA ARM: Analog Reliability Measurement based on Monte Carlo Analysis
Due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. Although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...
