A clock may refer to an oscillator that has been designed to provide a timing signal to facilitate operation of one or more synchronous processors In. An oscillator that works on negative resistance property can termed as a Negative resistance oscillator The term negative resistance refers to a condition where an increase in voltage across two points causes a decrease in current Some of the nonlinear devices exhibit negative resistance property, under certain conditions.

ATtiny microprocessors can use an internal RC oscillator or an external crystal oscillator External crystal oscillators are more accurate, but require two pins For these low pin count devices it can be beneficial to use the internal oscillator. Where t 1 is the output high duration, t 2 is the output low duration, T is the periodic time of the output waveform, ƒ is the frequency of the output waveform, and 0693 = ln(2) When connected as an astable oscillator, capacitor C charges through R A and R B but discharges only through R BThus the duty cycle D is determined by the ratio of these two resistors. This article discusses the good and the bad regarding Schmitt Trigger RC oscillators These oscillators are especially important because they are present in the internal oscillator in many popular MCUs.
