Abstract
A biasing circuit may include an input configured to receive a supply voltage, a value of which is higher than a limit voltage. The biasing circuit may also include a control stage configured to generate first and second control signals with mutually complementary values, equal alternatively to a first value, in a first half-period of a clock signal, or to a second value, in a second half-period of the clock signal. The first and second values may be a function of the supply and limit voltages. The biasing circuit may also include a biasing stage configured to generate a biasing voltage as a function of the values of the first and second control signals. The first and second control signals may control transfer transistors for transferring the supply voltage to respective outputs, while the biasing voltage may be for controlling protection transistors to reduce overvoltages on the transfer transistors.
