A technique for reducing jitter in an oscillating signal generated by an oscillator circuit includes reducing feedback of gate leakage current while increasing electrostatic discharge protection and reducing regulated power supply requirements of the oscillator circuit, as compared to conventional oscillator circuits. A circuit includes a first integrated circuit terminal and a thick gate native transistor of a first conductivity type having a first gate terminal having a first gate thickness. The first gate terminal is coupled to the first integrated circuit terminal. The thick gate native transistor has a first threshold voltage. The thick gate native transistor is configured as a source follower. The circuit includes a second transistor of the first conductivity type having a second gate terminal with a second gate thickness less than the first gate thickness. The second gate terminal is coupled to a source terminal of the thick gate native transistor.

An oscillator unit for a vehicle detector includes an oscillator circuit for generating vehicle detector loop signals in response to enabling control signals from a vehicle detector control unit, a gain control circuit for maintaining the amplitude of the oscillator output signals within a limited range, and a clamping circuit for eliminating ringing of the oscillator output signals when operation of the oscillator circuit is disabled. The gain control circuit eliminates random amplitude changes in the vehicle detector loop signals generated by the oscillator circuit caused by changing environmental conditions experienced by the vehicle detector loop. The clamping circuit provides immediate clamping of the oscillator circuit operation to eliminate ringing when the control signal switches to the off state. The few additional circuit components which provide the gain control and clamping functions add very little to the overall cost of the oscillator circuit.

A device and method for terahertz signal generation are disclosed. Oscillators are arranged in a two-dimensional array, each oscillator connected to a corresponding antenna.
