B. Razavi et al., DESIGN TECHNIQUES FOR LOW-VOLTAGE HIGH-SPEED DIGITAL BIPOLAR CIRCUITS, IEEE journal of solid-state circuits, 29(3), 1994, pp. 332-339
This paper describes design techniques for multigigahertz digital bipo
lar circuits with supply voltages as low as 1.5 V. Examples include a
2/1 multiplexer operating at 1 Gb/s with 1.2 mW power dissipation, a D
-latch achieving a maximum speed of 2.2 GHz while dissipating 1.4 mW,
two exclusive-OR gates with a delay less than 200 ps and power dissipa
tion of 1.3 mW, and a buffer/level shifter having a delay of 165 ps wh
ile dissipating 1.4 mW. The prototypes have been fabricated in a 1.5-m
um 12-GHz bipolar technology. Simulations on benchmarks such as freque
ncy dividers and line drivers indicate that for a 1.5-V supply, the pr
oposed circuits achieve higher speed than their CMOS counterparts desi
gned in a 0.5-mum CMOS process with zero threshold voltage.
