Abstract:
An oscillator for generating an oscillating signal, comprising:a first capacitor; a charging circuit portion for charging the first capacitor to a first high threshold voltage; a discharging circuit portion including a second capacitor for discharging the first capacitor to a low threshold voltage; a switching network to alternately connect the first capacitor to the charging circuit portion and the discharging circuit portion to thereby alternately charge and discharge the first capacitor; a set-reset flip flop, having a set input, a reset input, an output, and an inverted output, the set input coupled to the charging circuit portion, the reset input coupled to the discharging circuit portion, the output coupled to the switching network to control the charging of the first capacitor, the inverted output coupled to the switching network to control the discharging of the first capacitor.
