Resistor-capacitor oscillation circuit
A resistor-capacitor oscillation circuit includes a first group of inverters, a second group of inverters, a latch, a delay circuit, and a third group of inverters. The first group of the inverters is connected to the delay circuit and is configured to generate a first signal A and a second signal B. An input end of the second group of the inverters is connected to an enable signal EN. An output end of the second group of the inverters is connected to the latch. An output end of the delay circuit is connected to the latch. The latch is connected to the third group of the inverters and includes a first output end and a second output end. After a first clock signal FB is driven by the third group of the inverters, an output signal CLK is output by an output end of the third group.

Millimeter-scale bluetooth low energy transmitter with dual purpose loop antenna
A millimeter-scale Bluetooth low energy wireless transmitter is presented with a dual purpose loop antenna. The oscillator employs a high quality factor resonator formed by a printed 3.53.5 mm.sup.2 inductive loop antenna (simulated Q110) and an on-chip digitally-switched capacitor array (simulated Q283). The oscillator replaces the traditional voltage controlled oscillator plus power amplifier, achieving lower power consumption while maintaining phase noise of 118.5 dBc/Hz at 1 MHz offset that results in low FSK modulation error (2.1%) and low frequency drift during BLE packet transmission.

Resonant LC tank package and method of manufacture
A package on a die having a low resistive substrate, wherein the package comprises an inductor on low-k dielectric and a capacitor on high-k dielectric. The stacked arrangement having different dielectric materials may provide an inductor having a high Q-factor while still having a high capacitance density. In addition, moving the inductor from the die to the package and fabricating the high density capacitor on the package reduces the silicon area required permitting smaller RF/analog blocks on the chip.
