A continuity tester that indicates the resistance of, say, PCB traces with musically-related tones, whose pitch changes with ...
Abstract: D-band high speed communication applications require an amplifier with broad bandwidth and high power. The vacuum high-power amplifiers, however, exhibit a limitation in bandwidth, while ...
Abstract: This brief presents a four-channel amplifier featured by low-offset voltage and low input bias current, which is mainly used in high precision instruments. The amplifier consists of four ...
