Abstract
A method of designing an electronic circuit system with multiple Bipolar transistor is presented. With this method, the circuit parameters of the various components of the individual functional building blocks of the system are systematically adjusted to minimize the many deteriorating effects resulting from system-level interactions among these functional building blocks. In one embodiment, the method is applied to a Bipolar IC that is a Divide-by-16 divider where the functional building blocks are four Divide-by-2 dividers. The resulting improvement of output signal ripple from each divider stage is graphically presented. In another embodiment, the method is applied to another Bipolar IC that is a Bang Bang Phase Detector where the functional building blocks are three Master Slave D-Type Flip Flops. The resulting improvement of output signal ripple is also graphically presented.
