A delay-locked loop for outputting a precisely signal relative to an input reference signal includes a plurality of selectively controlled delay elements and a delay element control circuit, including a phase detector for detecting a phase shift between the input reference signal and the delayed output signal and producing an error signal. Each of the delay elements includes a first input associated with a negative output and a second input associated with a positive output, whereby the positive and negative outputs are selectively coupled to a constant voltage source responsive to a first bias voltage and to a ground. The positive and negative outputs are responsive to a second bias voltage and the first and second voltage inputs. The constant voltage source and the positive output are coupled via a first transistor and the constant voltage source and negative output are coupled via being a second transistor.

Common-bias and differential structure based DLL

A content addressable memory (CAM) has a CAM array and a CAM encoder. The CAM array in response to data stored in a memory address of the CAM array matching comparison data, produces a match signal corresponding to the memory address. The CAM encoder receives the match signal and using encoded cells, produces the memory address corresponding to the match signal.

Pipelined content addressable memory with read only element encoding scheme

An analog to digital converter having a group of subrange analysis blocks and reference voltage and offset voltage selection blocks. Each subrange analyses block produces an output representative of a range of bits in a digital output of the analog digital converter. The reference voltage and offset voltage selection blocks enable the operating conditions for the next subrange analysis block to be optimized for both linearity and operating speed.
