Abstract:
1. An inverter cell for a ring oscillator, the inverter cell comprising: a first transistor having a source, a drain, and a gate; a second transistor having a source, a drain, and a gate, wherein a first resistor having (i) a first end connected to the source of the first transistor and (ii) a second end connected to a first voltage potential; a second resistor having (i) a first end connected to the source of the second transistor and (ii) a second end connected to a second voltage potential that is different than the first voltage potential; and a capacitor having (i) a first end directly connected to the source of the first transistor and the first end of the first resistor and (ii) a second end directly connected to the source of the second transistor and the first end of the second resistor.
