Title: Relaxation oscillator
Inventor: OLA BRUSET
IPC: H03K3/0231
Filed: 2014-12-19
Abstract: The tail current provided to the input transistors 40-44 of the three-input differential circuit in a comparator used in a relaxation oscillator (figure 1) is increased as the ramp input signal 20 or 22 from one of the alternately charged and discharged capacitors (8,14, figure 1) reaches a voltage level sufficient to turn on one of the transistors 60,62, thereby allowing the current source 64 to augment the current source 50 and so improve the switching of the comparator when the ramp input signal 20 or 22 then exceeds the reference voltage on line 24. Improved switching speed and lower noise, and thus reduced oscillator jitter, may be obtained without a large current consumption.
