Low-power CMOS oscillator has push-pull output:  04/01/04 EDN Design Ideas Digital oscillators often generate TTL- or CMOS-level outputs, referred to ground. Generating a symmetric bipolar output with respect to ground presents a challenge. In this design, four 1.5V flashlight cells create ?3V voltage sources, and the midpoint of cells acts as the ground reference (Figure 1)....

Simple deadband generator targets push-pull drivers:  07/12/99 Electronic Design - Ideas for Design / In typical push-pull driver applications, the npn-pnp transistor pair is alternately turned on and off using a square-wave signal. A simple driver circuit uses an inverter betw1een the V1 and V2. . .
