Abstract

In some embodiments, a new DTS implementation, which employs the conventional Vbe/ΔVbe temperature dependent principles but substitutes a voltage-to-frequency (V/F) based ratio meter for the DAC based approach. This new approach can result in a more simplified circuit that may be more variation tolerant and can require less power and area.
