An all-digital multiphase DLL is presented that is robust to delay mismatch due to process variation. Each of four 90° phase shift blocks accurately align each phase to 90° delay using its own ring oscillator and locking delay code. Harmonic locking is protected by a ring oscillator and a counter. An area efficient binary to thermometer(More)
Two-photon nonlinear microscopy with the aid of plasmonic contrast agents is an attractive bioimaging technique capable of generating high-resolution images in 3 dimensions and facilitating targeted imaging with deep tissue penetration. In this work, physically synthesized gold nanoparticles containing multiple nanopores are used as 2-photon contrast agents(More)
