This means that the developed applications should as much as possible have no external components. One of the problems faced by the SoC design is the reaction of the semiconductor device to environmental elements such as the temperature. This work will concentrate on the development of an oscillator for a microcontroller. The device to be designed must be an on chip system and must be temperature insensitive. The oscillator has an output frequency of 6MHz, which is the typical oscillating frequency provided in a microcontroller. And can withstand a temperature range of 0°C to 70°C, which is the standard temperature range for commercial integrated circuit. The oscillator operates at a voltage range of 2.8V to 3.6V with a percentage error of -1.08% ~1.72%. The oscillator will make use of comparators to generate the output frequency. Sub-circuits including an LDO voltage regulator, current and voltage reference generator, and SR latch were designed to complete the oscillator circuit design. This work will also be elaborating on some existing technology related to a temperature compensated oscillator as well as a discussion on theories behind the effect of temperature to a CMOS device.
