However, its function is difficult to predict using normal transaction simulations before the device is put into diffusion. In this paper, we discuss a simple and effective simulation approach which ensures a successful start-up process in a self-biased temperature independent current reference. The circuit is implemented in a class-D power amplifier with a 0.35 #m BiCMOS process and the experimental result validates that, by using this method, the start-up success rate can be greatly improved to 100%.展开更多
