555 ramp generator. using current mirrors, the pnp mirror for the rising ramp and the npn for the falling ramp,
The slope of both sides of the ramp can be controlled independently by the resistors on the reference side of the current mirrors.....

Fine, because its a way were only one current source is active. That makes it easy to change independent rise and fall time from triangle to nice sawtooth forward and backward. Bookmarked!
