Abstract
A novel Schmitt trigger oscillator able to generate square/triangular wave is proposed. Its advantages are that the oscillation frequency and amplitudes are independent of not only temperature but also power supply voltage. Electronic adjustment of the oscillation frequency can be obtained with wide sweep range and DC offset adjustment available. In addition, the proposed scheme can produce frequency-constant derivative of PWM signal
