Abstract
A trinary inverter for a digital logic circuit of the type having relatively positive, negative and zero signal voltage values is implemented with CMOS transistors and has the advantages of low power dissipation and low output impedance in the zero signal state. The inverter comprises first, second and third inverter branches, where each branch is formed of a pair of complementary MOS field effect transistors. The inverted output signals from each branch are used to produce a device output signal having the desired voltage transfer characteristics.
