1. An integrated circuit block comprising:
- a first node;
a second node; and
a series arrangement of one or more capacitive elements and three or more switches coupled between the first node and the second node;
wherein;
the three or more switches are configured to withstand a voltage greater than a voltage withstood by one switch;
the three or more switches are configured to receive a control signal to enable or disable the switches and thereby adjusting the capacitance between the two nodes, andcompensation capacitive elements are coupled across at least one of the three or more switches.

Abstract
Devices and methods for improving voltage handling and/or bi-directionality of stacks of elements when connected between terminals are described. Such devices and method include use of symmetrical compensation capacitances, symmetrical series capacitors, or symmetrical sizing of the elements of the stack.
