... enabling the bus to drive a load up to 1400 pF or distance of 18 m on port A, and 400 pF on port B. Using the PCA9507 enables the system designer to isolate bus capacitance to meet HDMI DDC version 1.3 distance specification. The SDA and SCL pins are overvoltage tolerant and are high-impedance when ...

... When port A of the PCA9517A is pulled LOW by a driver on the I2C-bus, a comparator detects the falling edge when it goes below 0.3VCC(A) and causes the internal driver on port B to turn on, causing port B to pull down to about 0.5 V. When port B of the PCA9517A falls, first a CMOS hysteresis type in ...

... They gradually increase Vdd to compensate for NBTI degradation. Their technique has the potential to increase IC lifetime by 46% compared with guard-banding, while using 10 discrete voltage levels increase IC lifetime by 32.5%. However, their results were based on theoretic analysis. Scheduled techn ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
