Abstract
Impedance paths for integrated circuits having microelectromechanical systems (MEMS) switches that allow for electrical charge to bleed from circuit nodes to fixed electric potentials (e.g., ground) are described. Such paths are referred to herein as charge bleed circuits. The circuit nodes may be circuit locations where electrical charge may accumulate because there is no other path for the electrical charge to dissipate. In some embodiments, a charge bleed circuit includes a switchable device (e.g., a MEMS switch, a solid-state device switch, or a circuit including various solid-state device switches that, collectively, implement a device that can be switched on and off) that connects and disconnects the impedance path from a circuit node. This may allow the device to perform different types of measurements at desired performance levels.
