Abstract: | A low voltage full-swing BiCMOS bootstrapping technique that allows the design of BiCMOS logic circuits at supply voltages down to 1.5 V is presented. This is the first 1.5-V design technique that does not require complementary bipolar devices. The technique is shown to have significant advantages over existing low voltage BiCMOS logic designs in sub-3 V operation. Inverter gates fabricated using a 0.8-μm technology were operated at 150 MHz with a supply voltage of 1.5 V. Implementation of this technique on dynamic logic is also demonstrated and experimental results match closely with simulation |
