A temperature controlled phase compensation circuit may include a varactor coupled between a radio frequency (RF) transmission line and a node. A temperature controlled phase compensation circuit may include a resistance coupled between a voltage supply and the node, the voltage supply configured to supply a supply voltage. A temperature controlled phase compensation circuit may include a temperature controlled current source coupled to the node and configured to produce a capacitor voltage between the varactor and the resistance, wherein a capacitor voltage produced at the node and applied to the varactor is inversely related to temperature.

An electronic circuit including an amplifier, a first variable capacitance and a second variable capacitance. The amplifier receives an input signal across an inverting input terminal of the amplifier and a non-inverting input terminal of the amplifier. The first variable capacitance is electrically directly connected to the output terminal of the amplifier and the inverting input terminal of the amplifier. The second variable capacitance is electrically directly connected to the output terminal of the amplifier and the non-inverting input terminal of the amplifier.
