Abstract: A low-power oscillator based on a pulsed LC tank is
presented in this article. The frequency is determined by a bondwire inductor and a MiM capacitor to obtain a high-Q LC tank. Due to a novel way of driving the LC tank, the power consumption is diminished. Since the driving technique only interacts during a very short period with the LC tank, the frequency mainly depends on the stable LC tank and the temperature and supply voltage dependency is lowered drastically. The samples were measured over a 0.6 to 1.6V supply range and a -40 to 100C temperature range. A temperature dependency of 92 ppm/C and a voltage dependency of 73 ppm/V is obtained. The frequency standard deviation over 12 automatically bonded samples is 0.76% (359 KHz).
