Abstract :
A postamplifier with output buffer implemented in a standard 0.18μm 1.8V CMOS technology is proposed. Using broadband techniques for both postamplifier and output buffer, highspeed operation has been achieved. For a differential 10mVpp 231-1 pseudo random bit sequence, a bit error rate of 5·10-12 at 3.5Gbit/s has been measured. At lower bitrates the bit error rate is even lower: a 1 Gbit/s 10mVpp, input signal results in a bit error rate of 7·10-14. The rms jitter is 12ps. The postamplifier circuit consumes only 19mA from a 1.8V power supply.
