A circuit design for a Field Programmable Analog Array is presented which improves accuracy and repeatability compared to previous designs. Controlled by a configuration register, continuous-time signals are routed among programmable analog blocks to implement the user's chosen circuit. The configurable connections are realized by CMOS switches and a new… (More)
We report a renal cell carcinoma which presented as a metastasis to the larynx. The only preoperative clue to the diagnosis was its hypervascularity.
