Claims17
A low power consumption oscillator, comprising:
- an inverter connected to a high supply potential and to a low supply potential via two respective capacitors, each structured to have a substantially same leakage resistance in the range 100-1000 Mohm/μm2, and further comprising an amplifier having a succession of stages coupled to the inverter whereby outputs of two last successive stages maybe sampled.
An oscillator, comprising:
- an inverter having a first supply terminal, a second supply terminal, an input, and an output;
- a first capacitor coupled between the first supply terminal and a high supply potential and a second capacitor coupled between the second supply terminal and a low supply potential, the first and second capacitors each having a substantially same leakage resistance in the range of 100-1000 Mohm/μm2, and further comprising an amplifier having a succession of stages coupled to the inverter whereby outputs of two last successive stages maybe sampled.
