the voltage at the emitter is Vs -Vd + Vbe, so the collector voltage is that -Vsat of transistor (.2V?). What are you building?, looks like a sawtooth generator or such like. It is much better to use a miller integrator either with a transistor or an op-amp, this way you get a much larger and more linear saw tooth.
