A level shift circuit. A level shift circuit may include a first voltage supply control unit connected to a first voltage terminal to control a supply of a first voltage via a first and/or second path according to statuses of first and/or second input signals inputted differentially, a second voltage supply control unit connected to a second voltage terminal to control a supply of a second voltage via a first and/or second path, a switching unit controlling a connection between first and second voltage supply control units on a first and/or second path, and/or a buffer unit outputting an output signal corresponding to a first voltage and/or a second voltage in response to a first potential outputted between a first voltage supply control unit and a switching unit and/or a second potential output between a second voltage supply control unit and a switching unit.

A source driver of a display including a timing controller, the source driver and a display panel may include a digital-to-analog converter configured to output an analog value corresponding to a digital data signal supplied from the timing controller of the display panel. An amplification unit is configured to amplify the analog value in a switched capacitor mode to produce an amplified result, and to output the amplified result as a driving signal for driving a unit column line of the display panel. Therefore, since area and power consumption can be further reduced compared with a related source driver, costs can be reduced and Electromagnetic Interference (EMI) can be improved by the reduction of power consumption.

An oscillator including a current bias circuit and a ring oscillator. The current bias circuit tracks a temperature change of the oscillator by using a control voltage and generates a plurality of bias voltages to supply a bias current according to the temperature change. The ring oscillator compares differential output signals generated according to the bias voltages and generates an oscillation signal as a result of the comparison.
