Delay circuit and ring oscillator incorporating the same |
摘要 |
A delay circuit in accordance with the present invention includes: a first I2L inverter and a second I2L inverter connected in cascade with each other; and a capacitor interposed between a ground and a connecting point of the first and second inverters, wherein: the delay circuit further includes a current adjusting circuit having at least one third I2L inverter with a plurality of output terminals at least one of which is connected to an input terminal of the third I2L inverter; and the current adjusting circuit is connected to adjust a charge current of the capacitor. The configuration provides a delay circuit of simple circuit structure that accounts for a small area in an integrated circuit and that is capable of introducing any given delay and also provides a ring oscillator incorporating the delay circuit.
