Sažetak
High-voltage single-emitter (HV SE) Horizontal Current Bipolar Transistor (HCBT) with CMOS p - well RESURF region is analyzed with respect to its utilization in RF circuits. If compared to the high-speed (HS) HCBT, it retains the high- frequency characteristics to a certain extent due to the reduced base-collector capacitance by the full depletion of n -collector region, which is also accompanied by the breakdown voltage increase (e.g., BV CEO from 3.4 V to 10.5 V). The minimum noise figure NFmin of 1.2 dB at 0.9 GHz and 1.54 dB at 2.4 GHz is reported, which is by about 0.2 dB higher than in HS HCBT. Basically, the same linear operating area at low-voltage and high- current regions as in HS HCBT is achieved by transistor area increase, which is relevant for the Class-A power amplifiers. The examined device exhibits maximum output power of 19.3 dBm and gain of 17.3 dB in PldB at 0.9 GHz, IC=44.4 mA and VCE as high as 8 V. Therefore, the HV SE HCBT is shown to be suitable for the sub-5 GHz RF circuits, offering operation at higher VCE attractive for high-voltage applications such as access points.
