| dc.description.abstract | The study of this thesis is to design different power combiners for power amplifier
application, which can be used to achieve the high transmission efficiency and
impedance transformation. The content of this thesis is divided into two parts. They
are transformer and transmission line transformer (TLT) for power combining
respectively. In the first part, we have designed two power amplifiers with power
combining transformers. They are “A Parallel Power Combining Transformer for
CMOS Power Amplifier” and “Differential Class E Power Amplifier Using Power
Combining Transformer” respectively. The amplifiers were designed and
implemented in tsmcTM 0.18 μm CMOS process for 2.4 GHz application. The first
design is used of two class AB differential pairs, which were combined the output
power from four groups of amplifiers by parallel power combining transformer. And
the second design is used a class E differential pair, which were combined the output
power from the two class E amplifiers by the power combining transformer. The
second part of the thesis is related to the use of TLT for power combining in power
amplifier design. A K-band class AB differential power amplifier with TLT was
implemented in WINTM 0.15 μm pHEMT process.
The measured results of these designs are summarized as follow. The CMOS
power amplifier with parallel power combining transformer achieves a power gain of
19.8 dB, and input and output return losses are 10.2 dB and 5.3 dB respectively. The
output 1-dB gain compression point (P1dB) is 20.9 dBm, and the saturated output
III
power is 26.7 dBm with the maximum power added efficiency of 24.8%. The chip
size is 1.4 × 1.37 mm2. The differential class E power amplifier with power
combining transformer achieves apower gain of 12.98 dB. The output 1-dB gain
compression point (P1dB) is 23.3 dBm, and the saturated output power is 25.9 dBm,
with the maximum power added efficiency of 29.9%. The chip size is 1.33 × 1.11
mm2. The K-band Power Amplifier with TLT power combining network achieves a
power gain of 10.2 dB, and input and output return losses are 18.7 dB and 11.48 dB
respectively. The output 1-dB gain compression point (P1dB) is 22 dBm with the
power added efficiency of 23.4%. The chip size is 1.5 × 1 mm2.
