Abstract
An integrated circuit having a signal generator for generating an oscillating signal and a second element utilizing the oscillating signal. The signal generator is a ring oscillator having an odd number of active elements connected in series, where the signal output of one active element is connected to the signal input of the next active element to form a closed ring of active elements. Each active element has a power supply input and a ground connection, a signal input and a signal output, an inverter sub-element having a pair of current mirrors, and a capacitor controlled bias sub-element.
Claims8
An integrated circuit comprising a signal generator for generating an oscillating signal and a second element utilizing the oscillating signal, wherein said signal generator comprises a ring oscillator having an odd number of inverters connected in series, the output of one inverter being connected to the input of the next inverter to form a closed ring of inverters, each inverter having a power supply input and a ground connection, a signal input and a signal output, and power supply and a ground connection, and a signal input and a signal output, and with a current mirror inverter pair in signal input to signal output series between the signal input and signal output, and in head to tail series between the power supply input and the ground.
