Oscillator is based on the new architecture solution providing low power consumption and good stability over temperature range and voltage supply.
- Oscillator block consists of a low-power current-voltage reference circuit, comparator (operational amplifier), voltage controlled oscillator (5-stage current starved ring oscillator, VCO), frequency divider and frequency-to-voltage converter (FVC).
- Stability over voltage supply range from 1.2V to 1.8V and temperature range from -20o C to 85o C
- Schematic and layout design (GDS)
- Low power systems, target frequency 4 MHz
