A new BiCMOS Folded Source-Coupled Logic (Bi-FSCL) circuit is proposed. This is an improved version of CMOS Folded Source-Coupled Logic (C-FSCL). An Emitter Follower (EF) is implemented at the output of C-FSCL to obtain the Bi-FSCL gate. It has been shown that by using this EF, the output of the BiFSCL is faster than C-FSCL and capable of driving higher load (higher fan-out) at low supply voltage. Thorough current steering and charge storage analysis was performed for the folded source-coupled logic techniques. This paper focuses on simulated results based on a 2 /spl mu/m n-well BiCMOS process. The simulations were carried out using BSIM parameters at a supply voltage of 3.3 V. Implementation of a NAND/AND gate is also presented.
