The disclosure relates to a temperature-controlled oscillator. Embodiments disclosed include a temperature-compensated oscillator () comprising: a first capacitive charging circuit () connected between a supply voltage connection () and a common connection (), comprising a first transistor () and a first capacitor (), the first transistor () arranged to switch states when the first capacitor () is charged above a threshold voltage of the first transistor (); a second capacitive charging circuit () connected between the supply voltage connection () and the common connection (), comprising a second transistor () and a second capacitor () arranged to begin discharging when the first transistor () switches states, the second transistor () arranged to switch states when the second capacitor () is discharged below a voltage equal to a supply voltage (VDD) at the supply voltage connection () minus a threshold voltage of the second transistor (); and a third capacitive charging circuit () connected between the supply voltage connection () and the common connection (), comprising a third transistor () and a third capacitor () arranged to begin discharging when the second transistor () switches states, the third transistor () arranged to switch states when the third capacitor () discharges below a threshold voltage of the third transistor ().

Temperature-compensated oscillator

A sub-stage for a charge pump includes a dc input pin, a dc output pin, a first radio frequency (rf) input pin configured to receive a first differential signal, a second rf input pin configured to receive a second differential signal, a first transistor having first, second and third terminals, a second transistor having first, second and third terminals, a first bias voltage source, and a second bias voltage source. The third terminal of the first transistor is configured to receive the second differential signal from the second rf input pin and a first offset voltage signal from the first bias voltage source. The third terminal of the second transistor is configured to receive the second differential signal from the second rf input pin and a second offset voltage signal from the second bias voltage source.
