Latest Patents
S Chen Sean holds a patent for a "CMOS adjustable bandgap reference with low power and low voltage performance." This invention involves a voltage reference circuit designed using CMOS process-based technology to provide a configurable voltage reference. The circuit incorporates bipolar transistors that function as parasitic devices within the CMOS process. Two bipolar transistors are configured to generate a ΔVbe signal, which plays a crucial role in the voltage reference circuit. An error amplifier works in conjunction with these transistors through a control signal that is related to ΔVbe/R. Additionally, a first current source is connected to another bipolar device, which is parallel to a resistor divider. The output from this divider yields a divided reference signal that correlates with the Vbe of the other bipolar device. Another resistor connects a second current source to the output of the resistor divider, ensuring that an adjustable and temperature-compensated reference signal is produced.
