    摘要: During an ESD event, an ESD current flows from a ground node of a first ESD protection circuit and out of an integrated circuit to a terminal of a package that houses the integrated circuit. To improve ESD performance, a second ESD protection circuit is provided. A diode of the second ESD protection circuit is coupled between the ground node and the body of an input transistor of a Low Noise Amplifier (LNA). If the voltage on the ground node changes quickly during an ESD event (for example, due to a current spike flowing across a wire bond), then the diode charges the body of the transistor, thereby preventing a large gate-to-body voltage from developing across transistor. In some embodiments, another ground bond pad is provided and the second ESD protection circuit includes other diodes that charge or discharge other nodes during the ESD event to prevent transistor damage.

    摘要: A two-step tuning process for resistors and capacitors in an integrated circuit is described. In the first step of the tuning process, an on-chip adjustable resistor is tuned based on an external resistor to obtain a tuned resistor. The value of the tuned resistor is accurate to within a target percentage determined by the external resistor and the design of the adjustable resistor. In the second step, an adjustable capacitor is tuned based on the tuned resistor and an accurate clock to obtain a tuned capacitor having an accurate value. The adjustable capacitor may be tuned such that an RC time constant for the tuned resistor and the tune capacitor is accurate to within a target percentage determined by the accurate clock and the design of the adjustable capacitor. The resistors and capacitors of other circuits on the integrated circuit may be adjusted based on the tuned resistor and the tuned capacitor, respectively.
