Claim Text:
1. A linear triangular wave generator with stray effect compensation, comprising: a linear triangular wave generating module, comprising a first current source, and a physical capacitor and a stray component electrically connected to the first current source, the stray component being generated due to a stray effect of the first current source and the physical capacitor, the first current source charging/discharging the physical capacitor to generate a linear triangular wave signal; a negative impedance converting module, electrically connected to the linear triangular wave generating module, comprising a negative matching impedance for compensating an impedance of the stray component; an impedance sensing module, for sensing a matching level between the negative matching impedance and the impedance of the stray component; and a switching module, electrically connected to the negative impedance converting module and the impedance sensing module, including a first switching state and a second switching state for switching a sensing configuration of the impedance sensing module for the impedance sensing module to sense the matching level between the negative matching impedance and the impedance of the stray component.
