Detect wire breaks with unusual CMOS gate circuit

CMOS devices have large input impedance with input currents on the order of 0.01nA. Adding feedback circuitry can result in a latch-like device that can be used to store bits, and also operate in a ...

Power management can cause latchup in CMOS chips

If you leave signals applied to the inputs of a CMOS chip with the power turned off, the chip might explode when you re-apply power. This is called latchup. Similarly, if you drag the outputs of a ...

A bluetooth radio in 0.18um CMOS

A bluetooth radio in 0.18 um CMOS technology works on 2.5 - 3.0 V, dissipating 75 mW in RX and 90 mW in TX. RX uses a 2MHz IF with an active poly-phase bandpass filter. The fractional-N PLL uses a VCO ...
