Abstract: A temperature sensor is disclosed that determines whether the temperature of an integrated circuit (IC) is within a normal temperature range. A low threshold monitor circuit senses whether the temperature of the IC is above or below a minimum temperature threshold. A high threshold monitor circuit configured senses whether the temperature of an integrated circuit (IC) is above or below a maximum temperature threshold. The minimum temperature threshold is determined by an intersection of a first temperature coefficient of resistance (TCR) and a second TCR that are associated with a first pair of conductive lines. The maximum temperature threshold is determined by an intersection of a third TCR and a fourth TCR associated that are with the second pair of conductive lines.

Abstract: The techniques disclosed herein permit active, non-transparent management of financial assets within an exchange-traded fund while yielding the traditional advantages of scale and cost efficiency for secondary market participants. The fund may supplement traditional periodic disclosures of holdings with additional information to facilitate accurate intraday pricing of ETF shares. In this context, a substitute basket may be engineered and published on a daily basis that closely tracks the fund composition, but contains an active share of about 5-30% relative to the fund in order to obfuscate the actual fund holdings. This substitute basket may advantageously provide a high quality signal of fund value, while also facilitating in-kind transactions in the primary market that are closely related to the fund composition without revealing specific fund holdings or weightings.

Abstract: A temperature sensor is disclosed that determines whether the temperature of an integrated circuit (IC) is within a normal temperature range. The temperature sensor includes a low threshold monitor circuit and a high threshold monitor circuit. The low threshold monitor circuit senses whether the temperature of the IC is above or below a minimum temperature threshold. The high threshold monitor circuit configured senses whether the temperature of an integrated circuit (IC) is above or below a maximum temperature threshold. The low threshold monitor circuit includes a first pair of conductive lines, each having a different temperature coefficient of resistance (TCR) from the other; where the minimum temperature threshold is determined by an intersection of a first TCR and a second TCR that are associated with the first pair of conductive lines.
