In the Art of Electronics there is an assertion that if a bias is established with 0.5 the supply voltage, the transistor will saturate if the temperate goes up 8ºC. The schematic is the basic one for common emitter.
I tried to verify that the collector-emitter voltage became zero or less. However I can't manage to get it right. If we start by taking the V_BE voltage as 0.6, it would go down to .5832, but how can we use that to verify it saturates?
