This work presents an interpolated flying-adder-(FA-) based frequency synthesizer. The architecture of an interpolated FA, which uses an interpolated multiplexer (MUX) to replace the multiplexer in conventional flying adder, improves the cycle-to-cycle jitter and root-mean-square (RMS) jitter performance. A multiphase all-digital phase-locked loop (ADPLL)(More)
A new source follower circuit using low-temperature polycrystalline silicon thin film transistors (LTPS-TFTs) as analog buffer for the integrated data driver circuit of active matrix liquid crystal displays (AMLCDs) and active matrix light emitting diodes (AMOLEDs) is proposed and measured. Threshold voltage compensation circuit with two n-type thin film(More)
Electrostatic discharge (ESD) protection and latchup prevention are two important reliability issues to the CMOS integrated circuits, especially in high-voltage (HV) applications. In this work, the stacked low-voltage (LV) PMOS devices have been successfully verified in a 0.5-μm HV process to provide high ESD level with high holding voltage for HV(More)
