BIAS GENERATION AND DISTRIBUTION FOR A LARGE ARRAY OF SENSORS
Abstract:
In certain aspects, a bias generation circuit comprises a bias voltage generator. The bias voltage generator has a main NMOS transistor having a drain and a gate of the main NMOS transistor both coupled to a first terminal, a main resistor having a first main resistor terminal and a second main resistor terminal, wherein the first main resistor terminal couples to a source of the main NMOS transistor; and a main PMOS transistor having a source of the main PMOS transistor coupled to the second main resistor terminal and a drain and a gate of the main PMOS transistor both coupled to a second terminal, wherein the second terminal couples to a main ground. The bias generation circuit further comprises an array of sensors coupled to the first terminal and the second terminal.
