Latest Patents

Uehara holds a patent for a high-speed differential amplifier. This invention compares a potential difference between a first input (A.sub.in) and a second input (V.sub.r), providing complementary output signals (A, A). The differential amplifier includes a flip-flop circuit with nodes (N1, N2) and (N3, N4), along with a fixing means composed of N-channel FETs (33, 34). These FETs have drains connected to the nodes (N3, N4) of the flip-flop circuit and sources connected to a second potential (V.sub.SS). Additionally, inverters (31, 32) are utilized, with inputs receiving output signals (A, A) and outputs connected to the gates of the N-channel FETs. The fixing means detects potential drops in the output signals and stabilizes the nodes (N3, N4) to the second potential (V.sub.SS).
