A High-Performance OTA with Hybrid of Inverter-Based OTA and Nauta OTA for High Speed Applications
2021 IEEE International Symposium on Circuits and Systems (ISCAS), 2021Operational transconductance amplifiers (OTAs) are widely employed as active elements in filters, data converters, and buffer amplifiers. Inverter-based implementation of OTAs is an attractive approach for low voltage realization of analog subsystems.

Introductory Statement In 1938 Ota presented under the somewhat cryptic title of "nevus fusco-caeruleus ophthalmo-maxillaris," an unusual syndrome consisting of a grayish-blue, macular discoloration affecting the sclera of an eye and the ipsilateral facial skin in the area of the distribution of the corresponding trigeminal nerve. 38 There are earlier

The “nevus of Ota” is a hypermelanotic melanocytic phacomatosis, characterised by: (1) a (usually unilateral) area of non-hairy, macular or slightly raised hamartomatous hyperpigmentation (usually blue or grey in colour) involving the skin and mucous membranes at the forehead, temple, or eyelids over the distribution of the 1st and 2nd division of the ...

A slowly invasive naevus of Ota was followed for 50 yrs. During this time multiple biopsies were considered to be benign cellular blue naevus. The left globe, orbit, frontal bone and meninges were excised to achieve clearance.

ABSTRACTWe present the case of a 22‐year‐old woman, who had presented since the age of 15 a pale‐blue spot spread on the right‐hand side of her forehead and in her bulbar conjunctiva (first and second branches of the trigeminus nerve), consistent with Ota naevus.

The dialysis of Ochratoxin A (OTA)
Mycotoxin Research, 2001Standard dialysis did not result in a decrease of the OTA level in the blood serum of patients regularly treated by dialysis. Therefore, we examined the effect of dialysis on both OTA bound to the blood plasma proteins and free OTA. We carried out an in vivo experiment to determine OTA levels in the serum of patients in the terminal stage of chronic ...

ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002
The current-feedback OTA (CFB OTA) recently appeared in a new classification of operational amplifiers. It is dual to the operational floating amplifier (OFA), so all OFA circuits can readily be transposed into CFB OTA circuits. This paper discusses the theoretical basis of the CFB OTA, shows its relation to the OFA, and compares their performance in a
