The performance of P-n-p AlGaAs/GaAs heterojunction bipolar transistors (HBTs) for analog and digital circuit applications is compared to that of N-p-n HBTs. The theoretical analysis shows that the P-n-p HBTs are comparable with N-p-n HBTs in high-speed digital operation, while the N-p-n HBTs exhibit higher cut-off frequency in microwave and millimeter-wave operation. Analytical equations and SPICE circuit simulation are used in support of the comparison between the P-n-p and N-p-n HBTs. Optimization of device doping profile design for P-n-p and N-p-n heterojunction bipolar transistors in analog and digital circuits are presented.
