Title:
VOLTAGE CURRENT CONVERSION CIRCUIT AND VOLTAGE CONTROL OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2019/167353
Kind Code:
A1
Abstract:
This voltage control oscillator with a high power-supply voltage variation removal ratio and this voltage current conversion circuit of the voltage control oscillator make it possible to have low voltage operations. A cascode-connected transistor circuit supplies current to an output terminal. A potential generation circuit generates an operation potential of the cascode-connected transistor circuit from an input potential. The potential generation circuit comprises two transistors gates of which are connected to each other. The gate width of one of the transistors of the potential generation circuit is longer than the gate width of the other transistor. The potential generation circuit forms a feedback path for the cascode-connected transistor circuit.
