Abstract | ||
|---|---|---|
A 500 MHz -3 dB bandwidth linear amplifier in 65 nm CMOS at 1.2 V supply is presented for an amplitude modulator in a polar transmitter. The design uses a gain-boosting scheme for 105 dB DC gain at an 8 ¿ load and a buffered switching Class-AB bias scheme. It has 0.1 ¿ output impedance at 5 MHz and can drive 60 mA peak current. The chip efficiency is 83.5% and area is 1.35 mm2. |
