DEVICE FOR RECOVERY OF SIGNAL LEVEL IN CIRCUITS WITH PROGRAMMABLE SWITCHING Russian patent published in 2012 - IPC H03K17/00 

FIELD: radio engineering.

SUBSTANCE: device includes pull-up P-channel transistors, inverter, 2AND-NOR logic element and inverting delay line. Inverter includes P-channel transistor and N-channel transistor. 2AND-NOR element includes P-channel transistors and N-channel transistors. Inverting delay line includes odd number of in-series connected inverters each of which consists of P-channel transistor and N-channel transistor.

EFFECT: reduction of switching delay time and increase in curvature of front edge of signal, enlargement of range of supply voltages, increase in limit frequency of circuit operability and increase in noise threshold.
