摘要： Circuitry for providing an oscillating output signal. This circuitry includes a transconductance circuit having a first input, a second input, an output. The transconductance also includes a first transistor, a second transistor, and chopping circuitry. The chopping circuitry is for alternatively connecting, in a first clock cycle phase, a first node to a first terminal of the first transistor and a second node to a first terminal of the second transistor and, in a second clock cycle phase, following the first clock cycle phase, the first node to the first terminal of the second transistor and the second node to a first terminal of the first transistor. An oscillator circuit is also included and coupled to receive voltage from the output of the transconductance circuit, wherein the oscillating output signal is responsive to an output of the oscillator circuit. Further connected to the transconductance circuit are circuitry for providing a first voltage to its first input and a frequency controlled circuit for providing a second voltage to its second input.
