Abstract :
The paper describes design and structure of the Temperature-Controlled Oscillator for high frequency processors which work is based on information of present chip temperature. The task of the circuit is to stabilise required value of temperature of the silicon die and ensure safe work of the processor. The circuit consists of: temperature sensor, ring oscillator and some additional blocks to control the circuit behaviour. The prototype chip was designed and fabricated in CMOS LF 0.15 um (1.8 V) technology and is cooperating with an 8-bit OctaLynx microcontroller.
