This ... A frequency tuning circuit is introduced for VCOs (voltage-controlled oscillators) so that the final relationship between oscillating frequency and input control voltage is fixed and independent of nonidealities. This tuning loop is applied to an OTA-C sinusoidal VCO. Such an oscillator has an output frequency-input voltage relationship that depends on temperature, process parameters, and even amplitude of the oscillations. It is shown that, by adding the tuning loop, nonideal dependences will be minimized. |
