Abstract

In order to obtain an appropriate up-level output of the Current Controlled Gate (CCG) circuit [1, 2] the base of T4 is preferably supplied by a voltage in the order of 2.1 volts. The disclosed circuit generates the base voltage for T4 using resistor RCB connected to VRR and the current source of RCA and T6 connected to VCC (3.4 V) and VRR (1.7 V). A small current forced by the current source into node C causes a voltage drop across resistor RCB. This raises the base of T4 to the desired voltage. When node C is in its down level, the main current into node C is supplied by VRR via RCB. Only a small portion of the circuit current is contributed by VCC. Therefore, the power dissipation increase is small. References 1. A. H. Dansky, J. P. Norsworthy and C. D.
