An accurate design of a 2MHz oscillator for low voltage and low power applications is presented, demonstrating that the parasitic effects are determinant on the performance of high frequency RC oscillators. This RC circuit can operate in a power supply range of 1.8V to 3.2V with total current consumption of 14mA. The trimming is implemented by weighted-capacitors approach allowing better power saving and trimming linearity over 1.6 to 2.4MHz with a centered frequency of 2MHz.
