A MOS Temperature-Insensitive Voltage Divider and Its Application for Voltage Reference Design

We propose a MOS temperature-insensitive voltage divider circuit. The circuit works well in both weak inversion and strong inversion modes. The temperature insensitivity of this device is derived analytically and demonstrated by simulation. We also propose a voltage reference circuit based on the divider. We use a 90 nm CMOS Process DesignKit (PDK) to provide SPICE simulation.
