Yf. Yang et al., STATE HOLDING CIRCUIT USING HETEROJUNCTION BIPOLAR-TRANSISTORS AND RESONANT-TUNNELING DIODES, Electronics Letters, 30(1), 1994, pp. 90-92
A state holding circuit, similar to the Muller C-element used as a lat
ch, a register or a counter, has been successfully fabricated using Ga
As/AlGaAs heterostructures grown by molecular beam epitaxy (MBE). Usin
g the negative resistance in a resonant tunnel diode, the circuit has
a simpler configuration than the C-element and a potential for use in
high speed circuits.
